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…
The Strange Physics of Dark Baryons
Gonzalo Alonso-Álvarez, Gilly Elor, Miguel Escudero +3
Dark sector particles at the GeV scale carrying baryon number provide an attractive framework for understanding the origin of dark matter and the matter-antimatter asymmetry of the…
Probing the axion-nucleon coupling with the next generation of axion helioscopes
Luca Di Luzio, Javier Galan, Maurizio Giannotti +8
A finite axion-nucleon coupling, nearly unavoidable for QCD axions, leads to the production of axions via the thermal excitation and subsequent de-excitation of Fe-57 isotopes in t…
Earth Shielding and Daily Modulation from Electrophilic Boosted Dark Particles
Yifan Chen, Bartosz Fornal, Pearl Sandick +4
Boosted dark particles of astrophysical origin can lead to nonstandard nuclear or electron recoil signals in direct detection experiments. %It has been shown that this interpretati…
Stellar Evolution confronts Axion Models
Luca Di Luzio, Marco Fedele, Maurizio Giannotti +2
Axion production from astrophysical bodies is a topic in continuous development, because of theoretical progress in the estimate of stellar emission rates and, especially, because…
Supernova bounds on axion-like particles coupled with nucleons and electrons
Francesca Calore, Pierluca Carenza, Maurizio Giannotti +3
We investigate the potential of type II supernovae (SNe) to constrain axion-like particles (ALPs) coupled simultaneously to nucleons and electrons. ALPs coupled to nucleons can be…
