Dymnikova Black Hole Tidal Forces
M. H. Macêdo, A. A. M. Silva, R. R. Landim
In this work we investigate the tidal properties of the Dymnikova regular black hole and their ef fects on massive particles in radial free-fall. Starting from Dymnikova static, sp…
Cogenesis of baryon and lepton number asymmetries matching the EMPRESS Data
Kyu Jung Bae, Arghyajit Datta, Rinku Maji +1
We show that a simple supersymmetric extension of the standard model can explain simultaneously the large electron neutrino asymmetry hinted by the recent EMPRESS data…
Probing Right Handed Neutrino assisted Reheating with Gravitational Waves and Leptogenesis
Arghyajit Datta, Shaaban Khalil, Rajat Kumar Mandal +1
We investigate a non-instantaneous reheating period in the early Universe, where the inflaton field decays exclusively to right-handed neutrinos (RHNs). The subsequent decay of the…
Is leptogenesis during gravitational reheating flavourful?
Basabendu Barman, Arghyajit Datta, Md Riajul Haque
We examine the impact of charged lepton Yukawa equilibration on leptogenesis during gravitational reheating. During the post-inflationary era, the inflaton field is assumed to osci…
