Mass-varying Dark Matter from a Phase Transition
Sayan Mandal, Neelima Sehgal
We propose a mass-varying dark matter (MVDM) model consisting of a scalar field and a fermionic field interacting via a simple Yukawa coupling, and containing an exponential self-i…
Mass varying neutrinos with different quintessence potentials
Sayan Mandal, Gennady Y. Chitov, Olga Avsajanishvili +2
The mass-varying neutrino scenario is analyzed for three trial quintessence potentials (Ferreira-Joyce, inverse exponential, and thawing oscillating). The neutrino mass is generate…
Observationally inferred dark matter phase-space distribution and direct detection experiments
Sayan Mandal, Subhabrata Majumdar, Vikram Rentala +1
We present a detailed analysis of the effect of an observationally determined dark matter (DM) velocity distribution function (VDF) of the Milky Way (MW) on DM direct detection rat…
