Leptogenesis and neutrino mass with one right-handed neutrino and Higgs inflaton
Disha Bandyopadhyay, Debasish Borah, Suruj Jyoti Das +1
We propose a novel and minimal setup where the observed baryon asymmetry of the Universe and neutrino oscillation data can be satisfied with only one right-handed neutrino (RHN) an…
Cogenesis by a sliding pNGB with symmetry non-restoration
Eung Jin Chun, Suruj Jyoti Das, Minxi He +2
We demonstrate that a pseudo-Nambu-Goldstone boson (pNGB) with an initial misalignment angle can drive successful spontaneous baryogenesis and serve as a dark matter (DM) candidate…
Flipped Rotating Axion Non-minimally Coupled to Gravity: Baryogenesis and Dark Matter
Chao Chen, Suruj Jyoti Das, Konstantinos Dimopoulos +1
We demonstrate that the co-genesis of baryon asymmetry and dark matter can be achieved through the rotation of an axion-like particle, driven by a flip in the vacuum manifold's dir…
Hunting for heavy with IceCube neutrinos and gravitational waves
Basabendu Barman, Arindam Das, Suruj Jyoti Das +1
In the minimal gauged B-L extension of the Standard Model, we demonstrate that PeV-scale dark matter (DM) and the baryon asymmetry of the Universe (BAU) can be simultaneously expla…
Cogenesis of baryon and dark matter with PBH and QCD axion
Debasish Borah, Nayan Das, Suruj Jyoti Das +1
With entropy injection, an early matter-dominated epoch (EMD) impels the axion decay constant towards larger values to produce correct axion dark matter (DM) abundance, there…
