Constraints on neutrino-Majoron couplings using SN1987A data
Pilar Iváñez-Ballesteros, M. Cristina Volpe
Neutrino decay to a lighter neutrino and a massless or almost massless (pseudo)scalar Goldstone boson remains of wide interest, as in the search for ultralight dark matter or for n…
Neutrino non-radiative decay in matter: constraints and prospects
Pilar Iváñez-Ballesteros, M. Cristina Volpe
Neutrinos, being massive, can decay. A heavier neutrino could decay into a lighter one and a massless scalar or pseudoscalar boson, such as the Majoron. Two-body non-radiative deca…
Neutrinos from dense environments
M. Cristina Volpe
Neutrinos from dense environments are unique laboratories for astrophysics, particle physics and many-body physics. They tell us about the last stages of the gravitational core-col…
Diffuse Supernova Neutrino Background and Neutrino Non-Radiative Decay: a Bayesian Perspective
Noah Roux, M. Cristina Volpe
Neutrinos being massive could undergo non-radiative decay, a property for which the diffuse supernova neutrino background has a unique sensitivity. We extend previous analyses to e…
Neutrinos from dense environments : Flavor mechanisms, theoretical approaches, observations, and new directions
M. Cristina Volpe
Neutrino masses and mixings produce vacuum oscillations, an established quantum mechanical phenomenon. In matter, the Mikheev-Smirnov-Wolfenstein effect, due to neutrino interactio…
