In-flight positron annihilation as a probe of feebly interacting particles
Shyam Balaji, Pierluca Carenza, Pedro De la Torre Luque +2
Core-collapse supernovae (SNe) provide a unique environment to study Feebly Interacting Particles (FIPs) such as Axion-Like Particles (ALPs), sterile neutrinos, and Dark Photons (D…
rays from in-flight positron annihilation as a probe of new physics
Pedro De la Torre Luque, Shyam Balaji, Pierluca Carenza +1
The ray emission originating from in-flight annihilation (IA) of positrons is a powerful observable for constraining high-energy positron production from exotic sources. By com…
Comprehensive constraints on heavy sterile neutrinos from core-collapse supernovae
Pierluca Carenza, Giuseppe Lucente, Leonardo Mastrototaro +2
Sterile neutrinos with masses up to MeV can be copiously produced in a supernova (SN) core, through the mixing with active neutrinos. In this regard the SN 1987…
Spontaneous Lorentz symmetry breaking effects on GRBs jets arising from neutrino pair annihilation process near a black hole
Mohsen Khodadi, Gaetano Lambiase, Leonardo Mastrototaro
The study of neutrino pair annihilation into electron-positron pairs () is astrophysically well-motivated because it is a possible powering mechanism for the g…
Gravitational waves and neutrino oscillations in Chern-Simons axion gravity
Gaetano Lambiase, Leonardo Mastrototaro, Luca Visinelli
We investigate the modifications in the neutrino flavor oscillations under the influence of a stochastic gravitational wave background (SGWB), in a scenario in which General Relati…
Constraining axion-like particles with the diffuse gamma-ray flux measured by the Large High Altitude Air Shower Observatory
Leonardo Mastrototaro, Pierluca Carenza, Marco Chianese +4
The detection of very high-energy neutrinos by IceCube experiment supports the existence of a comparable gamma-ray counterpart from the same cosmic accelerators. Under the likely a…
Axion signatures from supernova explosions through the nucleon electric-dipole portal
Giuseppe Lucente, Leonardo Mastrototaro, Pierluca Carenza +3
We consider axions coupled to nucleons and photons only through the nucleon electric-dipole moment (EDM) portal. This coupling is a model-independent feature of QCD axions, which s…
Cosmological constraints on heavy sterile neutrinos
L. Mastrototaro
We consider heavy sterile neutrinos , with mass in the range 10 MeV MeV, thermally produced in the early universe and freezing out after t…
511 keV line constraints on feebly interacting particles from supernovae
Francesca Calore, Pierluca Carenza, Maurizio Giannotti +4
Feebly interacting particles with masses with O(10-100) MeV can be copiously produced by core-collapse supernovae (SNe). In this paper we consider the case of MeV-ish sterile neutr…
Massive sterile neutrinos in the early universe: From thermal decoupling to cosmological constraints
Leonardo Mastrototaro, Pasquale Dario Serpico, Alessandro Mirizzi +1
We consider relatively heavy neutrinos , mostly contributing to a sterile state , with mass in the range 10 MeV MeV, which are therma…
Heavy sterile neutrino emission in core-collapse supernovae: Constraints and signatures
Leonardo Mastrototaro, Alessandro Mirizzi, Pasquale Dario Serpico +1
Heavy sterile neutrinos with masses MeV mixing with active neutrinos can be produced in the core of a collapsing supernova (SN). In order to avoid an excessive…
