The neutrino magnetic moment and supernovae with strong magnetic fields
Clément Ehrhardt, Maria Cristina Volpe, Miguel Ángel Aloy +1
Despite several decades of searches, the neutrino magnetic moment remains unknown. If it is large, the neutrino evolution can be affected by its coupling to strong magnetic fields…
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…
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…
Using Bayesian Inference to Distinguish Neutrino Flavor Conversion Scenarios via a Prospective Supernova Neutrino Signal
Sajad Abbar, Maria Cristina Volpe
The upcoming galactic core-collapse supernova is expected to produce a considerable number of neutrino events within terrestrial detectors. By using Bayesian inference techniques,…
Neutrino nonradiative decay and the diffuse supernova neutrino background
Pilar Iváñez-Ballesteros, M. Cristina Volpe
The diffuse supernova neutrino background (DSNB) is the constant flux of neutrinos and antineutrinos emitted by all past core collapses in the observable Universe. We study the pot…
SN1987A and neutrino non-radiative decay
Pilar Iváñez-Ballesteros, M. Cristina Volpe
We investigate neutrino non-radiative two-body decay in vacuum, in relation to SN1987A. In a full decay framework, we perform a detailed likelihood analysis of the 24 neutrino…
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…
Neutrino non-radiative decay and the diffuse supernova neutrino background
Pilar Ivanez-Ballesteros, M. Cristina Volpe
We revisit the possibility that neutrinos undergo non-radiative decay. We investigate the potential to extract information on the neutrino lifetime-to-mass ratio from the diffuse s…
Neutrinos: from the r-process to the diffuse supernova neutrino background
Volpe Maria Cristina
Neutrinos from dense environments are connected to the longstanding open questions of how massive stars explode and what are the sites where -process elements are made. Flavor e…
Neutrino decoupling including flavour oscillations and primordial nucleosynthesis
Julien Froustey, Cyril Pitrou, Maria Cristina Volpe
We revisit the decoupling of neutrinos in the early universe with flavour oscillations. We rederive the quantum kinetic equations which determine the neutrino evolution based on a…
Fast Neutrino Flavor Conversion Modes in Multidimensional Core-collapse Supernova Models: the Role of the Asymmetric Neutrino Distributions
Sajad Abbar, Huaiyu Duan, Kohsuke Sumiyoshi +2
A dense neutrino gas, such as the one anticipated in the supernova environment, can experience fast neutrino flavor conversions on scales much shorter than those expected in vacuum…
Neutrino decoherence in presence of strong gravitational fields
Amélie Chatelain, Maria Cristina Volpe
We explore the impact of strong gravitational fields on neutrino decoherence. To this aim, we employ the density matrix formalism to describe the propagation of neutrino wave packe…

Sajad Abbar, Huaiyu Duan, Kohsuke Sumiyoshi +2
The dense neutrino medium in a core-collapse supernova or a neutron-star merger event can experience fast flavor conversions on time/distance scales that are much smaller than thos…
On Fast Neutrino Flavor Conversion Modes in the Nonlinear Regime
Sajad Abbar, Maria Cristina Volpe
A dense neutrino medium could experience self-induced flavor conversions on relatively small scales in the presence of the so-called fast flavor conversion modes. Owing to the fact…
Late time supernova neutrino signal and proto-neutron star radius
A. Gallo Rosso, S. Abbar, F. Vissani +1
We discuss the possibility of reconstructing the newly formed proto-neutron star radius from the late time neutrino signal. A black-body emission is assumed for the neutron star co…

Neutrino propagation in binary neutron star mergers in presence of nonstandard interactions
Amélie Chatelain, Maria Cristina Volpe
We explore the impact of nonstandard interactions on neutrino propagation in accretion disks around binary neutron star mergers remnants. We show flavor evolution can be significan…
