Nuclear Matrix Elements (NME) are a crucial input for the interpretation of neutrinoless double beta decay data. A representative set of recent NME calculations from different methods is taken, and a combined analysis of the available data performed in order to investigate the impact on the current and future sensitivities on the effective Majorana mass. A crucial role is played by the...
Ever since the discovery of neutrinos, we have wondered if neutrinos are their own antiparticles, and whether lepton number is violated or not. One remarkable possibility is that lepton-number violation in the Standard Model is soft. In such scenarios, neutrinos have a pseudo-Dirac nature with a tiny mass difference between active and sterile states, having oscillations driven by this tiny...
"Neutrinos from dense environments, non-radiative neutrino decay and the diffuse supernova neutrino background"
M. Cristina Volpe (CNRS/INP and APC, Paris)
In this talk I will first describe the frontiers of our knowledge on neutrino flavor evolution in dense media - core-collapse supernovae, binary neutron star mergers, early universe - and mention connections to other domains, in...
Earth neutrino tomography is a realistic possibility with current and future neutrino detectors, complementary to geophysics methods. The two main approaches are based on either partial absorption of the neutrino flux as it propagates through the Earth (at energies about a few TeV) or on coherent Earth matter effects affecting the neutrino oscillations pattern (at energies below a few tens of...
Euclid experiment will allow us to derive constraints on cosmological parameters and perform model selection through cross-correlation measurements between Cosmic Microwave Background (CMB) and Large Scale Structure (LSS). In this work we focalize on the detection of the late Integrated Sachs-Wolfe effect in order to constraint relevant cosmological parameters as the dark energy parameters and...
We derive new constraints on effective four-fermion neutrino non-standard interactions with both quarks and electrons. This is done through the global analysis of neutrino oscillation data and measurements of coherent elastic neutrino-nucleus scattering (CEvNS) obtained with different nuclei. In doing so, we include not only the effects of new physics on neutrino propagation but also on the...
Solar nuclear reactions can occasionally produce feebly interacting particles (FIPs) X that escape the solar interior without further interactions. In this talk, we focus on the second stage of the solar proton-proton chain and evaluate the fluxes of monochromatic 5.49 MeV FIPs produced by the p(d,He3)X reaction, analyzing the potential to detect them with the forthcoming large underground...
