Successful cogenesis of baryon and dark matter from memory-burdened PBH
Debasish Borah, Nayan Das
We study the possibility of producing the observed baryon asymmetry of the Universe (BAU) and dark matter (DM) from evaporating primordial black holes (PBH) beyond the semi-classic…
Large neutrino asymmetry from forbidden decay of dark matter
Debasish Borah, Nayan Das, Indrajit Saha
Dark matter (DM), in spite of being stable or long-lived on cosmological scales, can decay in the early Universe due to finite-temperature effects. In particular, a first order pha…
Collider and CMB complementarity of leptophilic dark matter with light Dirac neutrinos
Debasish Borah, Nayan Das, Sahabub Jahedi +1
We study the discovery prospects of leptophilic dark matter (DM) in future lepton colliders by considering the light neutrinos to be of Dirac type. Adopting an effective field theo…
Observable gravitational waves and with global lepton number symmetry and dark matter
Debasish Borah, Nayan Das, Rishav Roshan
We study the possibility of testing a dark matter (DM) scenario embedded in a global lepton number symmetry via gravitational waves (GW) and cosmic microwave background (C…
The Amaterasu particle: constraining the superheavy dark matter origin of UHECRs
Prantik Sarmah, Nayan Das, Debasish Borah +2
Amaterasu, the second most energetic ( EeV) cosmic ray particle has been recently detected by the Telescope Array (TA) surface detector. The origin of the TA Amaterasu event i…
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…
