Pion dark matter in a vacuum: a thermal relic with sharp velocity-dependent self-interactions
Camilo García-Cely, Giacomo Landini, Luca Marsili +1
As recently proposed, a non-vanishing topological angle may play a central role in QCD-like theories of dark matter (DM). In this work, we introduce a dark photon portal to the Sta…
Probing low-reheating scenarios with minimal freeze-in dark matter
Nicolás Bernal, Chee Sheng Fong, Óscar Zapata
The parameter space of freeze-in dark matter (DM) with mass through light dark photon (``minimal freeze-in DM'') is currently being probed by direct detection experiments thr…
Asymmetries from a charged memory-burdened PBH
Basabendu Barman, Kousik Loho, Óscar Zapata
We explore a purely gravitational origin of observed baryon asymmetry and dark matter (DM) abundance from asymmetric Hawking radiation of light primordial black holes (PBH) in pres…
Constraining burdened PBHs with gravitational waves
Basabendu Barman, Kousik Loho, Óscar Zapata
We investigate the implications of memory burden on the gravitational wave (GW) spectrum arising from the Hawking evaporation of light primordial black holes (PBHs). By considering…
