The Deep Underground Neutrino Experiment (DUNE) is a next-generation international experiment that will redefine our understanding of neutrino physics. The combination of a powerful wide-band neutrino beam complemented by a high-performance and movable near detector complex in Fermilab and a far detector with massive Liquid Argon Time Projection Chambers located 1,300 km deep at the Sanford...
The ND280 near detector of the T2K experiment at J-PARC plays a crucial role in minimizing the systematic uncertainties related to the neutrino flux and neutrino-nucleus cross-sections, as it measures the neutrino beam before it oscillates. The ND280 detector has recently been upgraded with a new suite of sub-detectors: a high-granularity SuperFGD with 2 million optically-isolated...
The next generation long-baseline neutrino experiment, Hyper-Kamiokande (HK) will rely on precise measurements of the neutrino and secondary particle interactions to reduce systematic uncertainties. The Water Cherenkov Test Experiment (WCTE), a 50-ton prototype operated at the end of the T9 beam line at CERN during 2024-2025, will deliver valuable measurements of processes relevant for...
The T2K experiment in Japan is a long-baseline neutrino oscillation experiment searching for CP violation in the leptonic sector. To enhance the precision of its measurements, the near detector ND280 has recently been upgraded with two new High-Angle Time Projection Chambers (HA-TPCs). The HA-TPCs improve the tracking of particles from neutrino interactions at high angles.
The HA-TPCs combine...
The Short-Baseline Near Detector (SBND) is one of the three experiments in the Short-Baseline Neutrino (SBN) Program at Fermilab. Located only 110 m downstream of the Booster Neutrino Beam (BNB) target, SBND is the detector closest to the neutrino source. The detector is a Liquid Argon Time Projection Chamber (LArTPC) with a 112-ton active volume which enables unprecedented precision...
The Short-Baseline Near Detector (SBND) is a 112-ton liquid argon time projection chamber 110 m away from the Booster Neutrino Beam (BNB) target at Fermilab (Illinois, USA). In addition to its role as the SBN program's near detector,enabling precision searches for short-baseline neutrino oscillations, the proximity of SBND to the BNB target makes the experiment ideal for many beyond the...
The NEXT experiment aims to detect neutrinoless double beta decay in $^{136}$Xe using a high-pressure gas Time Projection Chamber with electroluminescent amplification. This technology features an excellent energy resolution (<1% FWHM @ $Q_{\beta\beta}$) and the ability to extract topological information for background rejection. The physics program of NEXT-White, a ~5 kg detector, was...
The COLINA project aims to develop an innovative single-phase noble liquid time projection chamber (TPC) to detect CEνNS. Two distinct ideas are combined to maximize the potential of the technique. 1) The signal will be amplified through electroluminiscence (EL). 2) The TPC will be shaped as a conical frustum.
Single-phase EL is unaffected by charge trapping which is a major deterrent of...
We will show the complementarity between COHERENT and LHC searches in testing neutrino nonstandard interactions (NSIs) through the completion of the effective field theory approach within a Z′ simplified model. Our results reveal that LHC bounds are strongly dependent on the Z′ mass, with relatively large masses excluding regions in the parameter space that are allowed by COHERENT data and its...
NA64 is a fixed target experiment searching for Dark Sectors with the missing energy/momentum technique by employing high energy electron, positron, muon and hadron beams at the CERN Super Proton Synchrotron accelerator. In this talk, we focus on the status of the program using the high intensity M2 muon beamline. The first results obtained with $1.98\times10^{10}$ muons on target (MOT)...
DarkSide-20k is under construction at LNGS and is designed to lead the search for heavy WIMPs in the coming years. In addition to this, it has prospects to lead other DM searches and perform relevant detections of neutrinos from the Sun, the atmosphere, and Supernovae. Argon has the advantage of pulse shape discrimination compared to other noble elements, but has the drawback of the...
DEAP-3600 is an experiment performing direct dark matter searches since 2016. The detector has just undergone a third fill in order to achieve its goal sensitivity of 1e-46 cm2 for the WIMP-nucleon interaction cross section. This science case is achievable thanks to its location 2 km underground at SNOLAB, a thorough RnD to minimize its background and the background discrimination capabilities...
The evidence for the existence of dark matter from astrophysical observations is irrefutable. However, there has not been a conclusive direct detection of dark matter that does not rely on gravitational interaction with visible matter. One experiment, DAMA/LIBRA, claimed to have observed an annual modulation signal in a sodium-iodide-based detector consistent with that expected from dark...
TREX-DM (TPC for Rare Event eXperiments – Dark Matter) is designed for the direct search of WIMPs in the low-mass region. For the detection of these rare interactions, ultra-low background levels and a low energy threshold are required. TREX-DM meets these conditions by operating a high-pressure TPC filled with argon- (or neon-) based gas mixtures with a large microbulk Micromegas, chosen for...
HENSA is a high efficiency neutron spectrometer based on the same principle than Bonner sphere systems. The detector has been used for years in the Canfranc Underground Laboratory (LSC) in order to assess the neutron flux underground. In particular, for more than 3 years HENSA has been being used in hall B of the LSC with obejective to characterize the neutron flux that could affect the...
Axions and axion-like particles (ALPs) are well-motivated candidates to solve both the strong CP problem and the dark matter puzzle. One of the most promising experimental strategies to detect them is the axion helioscope, which searches for solar axions through their conversion into X-ray photons in a strong magnetic field. The International Axion Observatory (IAXO) is conceived as the...
In this talk, I explore how neutrinophilic dark sectors can impact core-collapse supernovae by extracting energy out of the proto-neutron star and show preliminary cooling bounds on two different models: a Dirac fermion with s-wave annihilation and a Majorana fermion with p-wave annihilation to neutrinos of all flavours. For each model I present the cooling bounds for two cases: a light...
We consider the possible production of a new MeV-scale fermion at the COHERENT, LZ and XENONnT experiments, and the future DUNE detector. The new fermion, belonging to a dark sector, can be produced through the up-scattering process of neutrinos off the nuclei and the electrons of the detector material, via the exchange of a light mediator. We explore the possibility of generalized...
We discuss the phenomenology of neutrino decoupling in the early universe, by summarising the details of the calculation in standard and non-standard scenarios. We show how non-standard physics can affect the amount of neutrinos that exist in the universe and how we can adopt cosmological observations in order to constrain neutrino properties such as their mass, effective number, interactions,...
Multi-messenger astronomy is an emerging field that aims to combine the information carried by different cosmic messengers (cosmic rays, photons, neutrinos, and gravitational waves) originating at a common source. Neutrinos, being stable and neutral particles, are especially valuable as they can escape dense environments. Furthermore, they are not absorbed during propagation to Earth and...
KM3NeT, a deep-sea Cherenkov neutrino telescope with MeV–PeV sensitivity, comprises two detectors: ARCA (high-energy astrophysical neutrinos) and ORCA (low-energy oscillations/atmospheric studies). With roughly 25% of the detectors deployed, it is partially operational, and the full completion is expected by the end of the decade.
Its design provides a large field of view including the...
Nowadays, deep-sea neutrino telescopes, e.g. KM3NeT, are based on the detection of the Cherenkov light produced after a neutrino interaction by a large 3D array of optical sensors. These detectors also have an acoustic system associated for monitoring the position of optical sensors. In this paper, we discuss the possibility of using the acoustic sensors of the positioning system for the...
KM3NeT is a next-generation neutrino telescope currently under construction in the Mediterranean Sea. It consists of two detectors, ARCA and ORCA, both equipped with multi-PMT optical modules designed to detect the Cherenkov light produced by charged particles originating from neutrino interactions in the surrounding medium. ARCA, optimized for energies from TeV to PeV, is dedicated to the...
The Cherenkov Telescope Array Observatory (CTAO) is an international project aimed at advancing our understanding of the gamma-ray sky with the most sensitive gamma-ray observatory ever built. CTAO will consist of two arrays of Imaging Atmospheric Cherenkov Telescopes (IACTs), comprising more than 60 telescopes in total. The northern array is under construction at the Roque de los Muchachos...
Extreme high-synchrotron-peaked blazars (EHSPs), defined by synchrotron peaks above 10^17 Hz, represent an uncommon subclass of blazars that challenge conventional blazar emission models and probe the limits of particle acceleration in relativistic jets. Yet, the number of identified EHSPs remains small, limiting comprehensive studies of their population and physical characteristics. In this...
Light primordial black holes (PBHs) may have originated in the early Universe, and could contribute to the dark matter in the Universe.
Their Hawking evaporation into particles could eventually lead to the production of antinuclei, which
propagate and arrive at Earth as cosmic rays with a flux peaked at GeV energies.
In 2505.04692 we revisit the antiproton and antideuteron signatures from...

En los años 80, J. Linsley sugirió la posibilidad de usar, como alternativa a las macroredes de detectores para la deteccion de rayos cosmicos de altas energia, pequeñas redes de detectores con capacidad de medir la anchura temporal y la densidad de particulas de los frentes de las cascadas astmosfericas y alguna parametrización conocida. Cuatro décadas mas tarde se ha avanzado...
The Short-Baseline Near Detector (SBND) is a 112-ton liquid argon time projection chamber (LArTPC) located 110m from the Booster Neutrino Beam target at Fermilab, serving as the near detector of the Short-Baseline Neutrino program. It also incorporates a photon detection system (PDS) with a dual-readout design featuring 120 photomultiplier tubes (PMTs) and 192 X-ARAPUCA devices that...
