The formation history of supermassive black holes (SMBHs) influences the surrounding distribution of dark matter (DM). While slow, adiabatic growth is known to produce high DM density regions referred to as “spikes,” more realistic formation scenarios, such as collapse from a stellar progenitor, generate weaker overdensities called “mounds”. Upcoming gravitational wave (GW) detectors will be...
MUTE (MUon inTensity codE) is a Python program that performs calculations for cosmic-ray muons underground and underwater. It combines two state-of-the-art programs, DAEMONFLUX and PROPOSAL, to provide comprehensive calculations for muon intensities, total muon fluxes, energy and angular spectra, and mean muon energies at the surface, in deep underground laboratories — under both flat...
The NA62 experiment at CERN is designed to measure the highly-suppressed decay $K^{+} \to \pi^{+}\nu\bar{\nu}$ and has collected a large sample of $K^+$ decays in flight during Run 1 (2016-2018) and Run 2 (since 2021). Searches for the decay $K^{+}\rightarrow\pi^{+}X$ using data from 2016-2022, set upper limits on the branching ratio at the $10^{-11}$ level, constraining a broad range of New...
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...
The recent observation of Coherent Elastic Neutrino–Nucleus Scattering (CE$\nu$NS) from solar $\rm ^8B$ neutrinos by dark matter direct detection experiments marks the first identification of the so-called “neutrino floor”. Far from being a mere background for dark matter searches, this signal opens a novel window to probe light new physics.
In this talk, I will present new constraints on...
Neutrinoless double-beta decay is a hypothetical nuclear process, (A,Z) → (A,Z+2) + 2e⁻, that is not allowed by the Standard Model since it violates the total lepton number conservation by two units.
The discovery of 0νββ would have profound theoretical implications: it could help explain the matter-antimatter asymmetry in the universe and it is the only practical way to determine if the...
Strong Interacting Massive Particles are a well motivated DM candidate. In particular we took into consideration a QCD-like theory with three flavours, where the DM candidate is a dark pion. In Ref[2405.10367], it has been found that a non-vanishing theta angle would trigger resonant processes which would give rise to the observed relic density, together with providing velocity dependent...
