        RGEs and positivity bounds of the SMEFT dimension-8 operators 20m

        The Standard Model effective field theory (SMEFT) is one of the preferred approaches for studying particle physics in the present scenario. The dimension-six SMEFT operators are the most relevant ones and have been studied in various works. The renormalization group evolution equations of these operators are available in the literature and facilitate examining the SMEFT on combined experimental information gathered across different energy scales. But, the dimension-six operators are not the dominant term for all observables, and some of these operators are loop-generated when UV theories are matched to the SMEFT. Also, considering that for relatively low values of the cut-off scale of the SMEFT, contributions from dimension-eight operators cannot be neglected.

        In this work, we present the renormalization of the bosonic sector of the dimension-eight operators by tree-level generated dimension-eight operators in the matching of weakly coupled UV theories to the SMEFT. These operators appear in the positivity constraints, which determine the signs of certain combinations of Wilson coefficients based on the unitarity and analyticity of the S-matrix. These constraints are remarkably significant as any experimental evidence of a violation of these constraints might indicate the invalidity of the EFT approach, such as, for example, the existence of lighter degrees of freedom below the cut-off scale of the EFT. Also, on the other hand, these restrictions can be taken into account while defining priors on the fits aiming at constraining the SMEFT parameter space.

        WW resonances as a window to Higgs physics 20m

        The appearance of resonances in the spectrum of longitudinally polarized WW scattering would be a clear indication of the existence of a New Physics (NP) sector that is described by strong interactions. These processes, emerging in pp collisions, are intimately related to the Higgs mechanism so it seems natural to study the features of the Higgs boson and its potential if one wants to test this supposedly strongly interacting theory (SIT) at high energies. In this talk I will present an effective framework that describes the dynamics of the SIT at low energies reachable at the LHC, and how, in fact, the predictions for resonant states can help to set phenomenological bounds on the Higgs self-couplings, and hence the Higgs potential.

        Phenomenological implications of the NLHT 20m

        In this talk we will briefly review the New Littlest Higgs model with T-parity (NLHT). This is introduced to cure the pathologies of the Littlest Higgs model with T-parity (LHT) in the fermionic sector. As a result of this, the NLHT includes new T-odd scalar particles and heavy fermions. The scalar fields receives their masses from the Coleman-Weinberg potential, independent of the scale of spontaneous breaking of the global symmetry f, and thus potentially light. The extra heavy fermions recieve their masses from a new Yukawa Lagrangian while the top sector is realized similarly to that of the LHT. To constraint the model parameter space, we work in a simplified version with degenerate Yukawa couplings for heavy leptons and quarks. Imposing that no mass exceeds the cutoff scale, current bounds on vector-like quarks and heavy lepton masses compatible with the stable dark photon as our dark matter candidate, we get that the scale f and the particle spectrum is bounded from below and above, the Yukawa coupling of heavy leptons gets fixed and the Yukawa coupling from quarks becomes greatly correlated to the top quark Yukawa couplings. We also study the dominant new T-odd scalar fields decay channels and lifetime.

        The dynamics of domain wall strings 20m

        In many field theories, solitonic solutions admit localized excitations with unnaturally long lifetimes in their spectrum of perturbations. These bound states may play a significant role in the dynamics of solitons, and in particular, they could shed light on some aspects concerning the evolution of cosmic string networks. In this talk I will discuss the influence of this type of excitations on the dynamics of string-like domain walls in 2+1 dimensions, focusing mostly on interesting resonance phenomena arising from the interaction of different modes at a non-linear level. The processes by which the excited string can emit radiation will also be analyzed, and the motion of the soliton in lattice field theory simulations will be contrasted with the one predicted by the Nambu-Goto action.

        Constraints to the 2HDM soft breaking parameter $m_{12}$ in the di-photon Higgs decay 20m

        Within the 2HDM, it is usual to impose a $Z2$ symmetry to avoid the presence of flavor-changing neutral currents in the model at the tree level. This symmetry can be softly broken by a term in the Lagrangian proportional to a new parameter $m_{12}$. This parameter introduces a new energy scale in the model and is only present in the scalar interactions of the 2HDM. We explore the possible sensitivity to this parameter $m_{12}$ from the di-photon decay of the SM-like Higgs boson. We conclude that, with the present data, this decay can set additional bounds on $m_{12}$ at the 95% CL while respecting the rest of the relevant constraints of the model. Furthermore, we also show that the new measurement of the $W$ boson mass has a lesser impact on the derived limits.

        Consistent Kinetic Mixing 20m

        Extensions of the Standard Model (SM) with new Abelian gauge groups allow for
        kinetic mixing between the new gauge bosons and the hypercharge gauge boson,
        resulting in mixing with the photon. In many models the mixing with the
        hypercharge gauge boson captures only part of the kinetic mixing term with the
        photon, since the new gauge bosons can also mix with the neutral component of
        the $SU(2)_L$ gauge bosons. We take these contributions into account and present
        a consistent description of kinetic mixing for general Abelian gauge groups both
        in the electroweak symmetric and the broken phase. These contributions are
        relevant for all hidden photon models in which SM fermions are charged, like
        $U(1)_{B-L}, U(1)_{L_i-L_j}$, etc.
        Based on these results we derive a low-energy theorem for the couplings of novel
        Abelian gauge bosons with the Standard Model Higgs boson from the one-loop
        kinetic mixing amplitudes.

        The vector boson spectrum at LHC 20m

        Z and W boson production are fundamental processes at LHC. Theoretically higher order perturbative calculations also have been computed. The precision achieved by LHC data shows however the emergence of non-perturbative effects and new multi-dimentional hadronic structures, beyond PDF. I will discuss the current status of this research and its impactin current observables and future studies both at LHC and EIC (Electron Ion Collider).

        Study of heavy quark-antiquark in-medium potentials 20m

        One of the greatest challenges in physics is to study quantum field theories (QFT) outside the perturbative regime. In particular, to better understand quantum chromodynamics (QCD), the theory that describes the strong nuclear force, in the non-perturbative regime, there are numerous tools available, among which the open quantum systems (OQS) formalism stands out. The quintessential case of this formalism of a subsystem interacting with the environment has a one-to-one equivalence in a system of a hadron immersed in a quark-gluon plasma (QGP). OQS requires the use of a potential and the study of how it is modified by the presence of a medium. Here, we present a general method for the derivation of in-medium potentials starting from its vacuum form. Using the generalised Gauss’s law, together with the introduction of the concept of permittivity, the general form of a potential in the medium is derived by requiring the vacuum case to be recovered. The whole development will then be applied to a particular case, the particle X(3872), and it will be seen that the results obtained – especially the melting temperature of this state – are consistent with state-of-the-art calculations for similar systems.

        The three-gluon vertex in Landau gauge for general kinematics 20m

        The three-gluon vertex plays a central role in the infrared dynamics of Quan-
        tum Chromodynamics (QCD). Gluon self-interaction shows the main diference
        between this theory and others like quantum electrodynamics (QED), its non-
        abelian nature. The appearance of a three-gluon vertex in the QCD Lagrangian
        is intimately linked to both asymptotic freedom and con?nement in QCD. The
        study of its non-perturbative features has attracted attention for the last decades
        in both Dyson-Schwinger and lattice simulations. The three gluon vertex de-
        pends on the incomimg momenta, q, r and p, with the kinematical constrain
        q + r + p = 0. Most lattice studies focus in the symmetric (q2 = r2 = p2) and
        soft-gluon (p = 0, and thus q2 = r2) cases where there is a single momentum
        scale. Both kinematics exhibit an infrared zero-crossing which can be under-
        stood as a consequence of the gluon-mass generation while the ghost remains
        massless.
        In this work, we present recent results for the three-gluon vertex from quenched
        lattice-QCD in extended kinematics, i.e., beyond the limiting previously studied
        cases. From our lattice results, two outstanding features of the non-perturbative
        three-gluon vertex emerge:
        ˆ the form-factor associated to the tree-level tensor is clearly dominant over
        the others
        ˆ the scalar form factors depend almost exclusively on the symmetric vari-
        able s
        Being its study of paramount theoretical relevance by itself, the three-gluon
        vertex is also a central component in a variety of phenomenological studies in the
        continuum. This ongoing search, based on the pro?table synergy between lat-
        tice simulations and continuum methods, has a?orded a ?rmer grip on delicate
        underlying patterns, establishing prominent connections with the emergence of
        a mass-scale in the gauge sector of the theory.

        Testing entanglement and Bell Inequalities in H --> ZZ. 20m

        We discuss quantum entanglement and violation of Bell inequalities in the H --> ZZ decay, in particular when the two Z-bosons decay into light leptons. Although such process implies an important suppression of the statistics, this is traded by clean signals from a "quasi maximally-entangled" system, which makes it very promising to check these crucial phenomena at high energy. We devise a novel framework to extract from H --> ZZ data all significant information related to this goal, in particular spin correlation observables. In this context, we derive sufficient and necessary conditions for entanglement in terms of only two parameters. Likewise, we obtain a sufficient and improved condition for the violation of Bell-type inequalities. The numerical analysis shows that with a luminosity of L = 300 fb^{-1} entanglement can be probed at > 3σ level. For L = 3 ab^{-1} (HL-LHC), entanglement can be probed beyond the 5σ level, while the sensitivity to a violation of the Bell inequalities is at the 4.5σ level.

        Cosmological analogies in the search for new physics in high-energy collisions 20m

        Correlations play a fundamental role in many branches of physics, from quantum mechanics to particle physics and cosmology. In particular, the astonishing homogeneity of the angular distribution of the Cosmic Microwave Background (CMB) radiation across the sky (measured with high precision by WMAP and Planck missions) requires of an inflationary epoch right after the Big Bang to solve the horizon problem. However, still some anomalies like the lack of positive large-angle correlations show up in the study of the CMB, likely indicating the need of a better understanding of the universe evolution.
        Angular correlations in high-energy collisions also could play an important role to uncover a possible non-conventional stage of matter (e.g. from Hidden Valley models) produced on top of the QCD partonic cascade followed by final hadronization. Indeed, new physics beyond the SM could stretch and enhance (pseudo)rapidity and azimuthal 2- and 3-particle correlations in high-energy collisions. We explore a suggestive cosmological analogy together with the physical potential of this technique to detect new physics in hadronic collisions at the LHC, and more cleanly at future e+e- colliders.

        Application of a quantum algorithm for querying causality 20m

        A quantum algorithm application for Feynman loop integrals is illustrated. We present a proper modification of Grover's algorithm for the identification of causal singular configurations of multiloop Feynman diagrams. The quantum algorithm is implemented in a quantum simulator, the output obtained is directly translated to causal thresholds needed for the causal representation in the loop-tree duality.

        Variational Quantum Eigensolver for Feynman Diagrams 20m

        We present a variational quantum eigensolver (VQE) algorithm for the efficient bootstrapping of the causal representation of multiloop Feynman diagrams in the Loop-Tree Duality (LTD) or, equivalently, the selection of acyclic configurations in directed graphs. A loop Hamiltonian based on the adjacency matrix describing a multiloop topology, and whose different energy levels correspond to the number of cycles, is minimized by VQE to identify the causal or acyclic configurations. The algorithm has been adapted to select multiple degenerated minima and thus achieves higher detection rates. A performance comparison with a Grover's based algorithm is discussed in detail. The VQE approach requires, in general, fewer qubits and shorter circuits for its implementation, albeit with lesser success rates.

        Caracterización y modelado de SiPM en GAE-UCM 20m

        Los fotomultiplicadores de silicio (SiPMs) cada día tienen mayor aplicación en física de altas energías (p.ej., en Medicina Nuclear, telescopios Cherenkov para astronomía de rayos gamma, y detectores en colisionadores de partículas). No obstante, algunos aspectos de la respuesta de SiPMs, en particular en el régimen no lineal, aún no son del todo bien entendidos. El Grupo de Altas Energías (GAE) de la UCM lleva trabajando varios años en la caracterización y modelado de la respuesta de estos detectores [1, 2, 3].
        En esta ponencia se presentarán los últimos avances que ha realizado el GAE en el modelado de la respuesta no lineal de los SiPMs. Se describirá resumidamente un modelo matemático [3] que tiene en cuenta todos los procesos que contribuyen a la no linealidad del detector: el número finito de microceldas del dispositivo, el tiempo de recuperación, el crosstalk, el afterpulsing y el ruido no correlacionado. Se explicará cómo usar este modelo para caracterizar la respuesta del detector en un caso práctico, en función de unos pocos parámetros efectivos que pueden medirse fácilmente en cualquier sistema experimental. Una ventaja importante de este modelo es que tiene en cuenta adecuadamente la dependencia de la respuesta no lineal del con la forma temporal de los pulsos de luz.
        Se expondrá el trabajo que está llevando a cabo actualmente para la mejora de este modelo, así como su validación con simulaciones de Monte Carlo y con valores experimentales. Por último, se comentarán las expectativas del GAE en esta línea de investigación.

        Radiation detectors for advanced particle therapy 20m

        Consuelo Guardiola, Celeste Fleta, Giulio Pellegrini, Faustino Gómez, and Manuel Lozano

        New detection systems for microdosimetry and FLASH therapy have been developed and successfully tested at the Orsay Proton Therapy Center (CPO, France) and the National Metrology Institute (PTB, Germany) respectively. They are based in novel silicon 3D-cylindrical microdetectors and silicon carbide (SiC) designed and manufactured at the Centro Nacional de Microelectrónica (IMB-CNM, CSIC) in Barcelona, Spain.

        On the one hand, the former has a cylindrical shape with a size comparable to that of the nuclei of human cells (20 µm-thick, 25 µm-diameter). On the other hand, the SiC is a very promising material for hard radiation detectors, as those required in FLASH therapy. Both detectors have been specifically customized for being used in particle therapy, overcoming some of the technological challenges in this domain, namely the low noise capability, well-defined sensitive volume, high spatial resolution and pile-up robustness.

        We present here the results of the first dosimetry measurements performed with both detectors in standard proton therapy and FLASH conditions. Both systems can have a positive impact in clinical treatments: the Si microdosimeters can reduce the radiobiological uncertainties in the normal tissue surrounding the target by allowing for further RBE calculations; the SiC detectors aim to be the first active dosimeter working at ultra-high dose rates. Additionally, it can be employed for commissioning accelerators and radiation protection for spacecraft, i.a.

        New commercial-ready particle detector technologies at IMB-CNM (CSIC) 20m

        Daniela Bassignana, Miguel Ullán, Giulio Pellegrini, Salvador Hidalgo, Celeste Fleta, and Manuel Lozano

        During the last years, we have been upgrading the Micro-Nano Fabrication Clean Room of the IMB-CNM (CSIC) to process 15 cm wafers. This has compelled us to redevelop our standard technologies (as pad detectors, AC and DC coupled microstrip detectors, pixel detector or 3D-pixels) for the new wafer size using new equipments.

        In parallel, we have stabilized new particle detector technologies so we can now offer them at a “commercial-ready” status. We can mention in this category Low-Gain Avalanche detectors, ultra-shallow junction diodes for very low energy particles, resistive electrode detectors, Silicon Carbide diodes or microchannels for detector cooling.

        In this talk we will present these new developments that could be of interest to the Spanish CPAN community of any other particle or nuclear laboratory in the world.
