Dark Matter Interpretation of the Super-Kamiokande Antineutrino Excess and Predictions for JUNO
Alessandro Granelli, Silvia Pascoli, Salvador Rosauro-Alcaraz
Super-Kamiokande has reported a small excess of electron antineutrino events in the 20 MeV energy range, in the search for the diffuse supernova neutrino background. We interpret t…
Interpreting the results on exclusive modes
D. Bečirević, M. Martines, S. Rosauro-Alcaraz +1
We examine the -binned distributions of the decay rate and of the corresponding forward-backward asymmetry which were recently measured by BESIII, showing a mild de…
Cosmological phase transitions: from particle physics to gravitational waves, semi-analytically
S. Pascoli, S. Rosauro-Alcaraz, M. Zandi
Motivated by the recent evidence of a stochastic gravitational wave background found by pulsar timing array experiments, we focus on one of the prime cosmological explanations, i.e…

From oversimplified to overlooked: the case for exploring Rich Dark Sectors
Asli Abdullahi, Francesco Costa, Andrea Giovanni De Marchi +9
The Standard Model (SM) of particle physics provides a very successful description of fundamental particles and their interactions but it is incomplete, as neutrino masses, dark ma…

The presence of a dark matter component in the Universe, together with the discovery of neutrino masses from the observation of the oscillation phenomenon, represents one of the mo…
Supercooled Dark Scalar Phase Transitions explanation of NANOGrav data
Francesco Costa, Jaime Hoefken Zink, Michele Lucente +2
The evidence of a Stochastic Gravitational Wave Background (SGWB) in the nHz frequency range is posed to open a new window on the Universe. A preferred explanation relies on a supe…

Lukas Allwicher, Damir Becirevic, Gioacchino Piazza +2
Recently, Belle II reported on the first measurement of which appears to be almost larger than predicted in the Standard Model. We point o…
Thermal effects in freeze-in neutrino dark matter production
A. Abada, G. Arcadi, M. Lucente +2
We present a detailed study of the production of dark matter in the form of a sterile neutrino via freeze-in from decays of heavy right-handed neutrinos. Our treatment accounts for…
