Dark matter, neutrino mass and baryogenesis in the radiative seesaw model | | Pritam Das

13 Jan 2020 | | Abstract: | We study the simplest viable dark matter model with an additional neutral
real singlet scalar, including a vectorlike singlet and doublet fermions. We
find a considerable enhancement in the allowed region of the scalar dark matter
parameter spaces in the presence of these fermions. The decay of the lightest
component of the fermion doublet enhances the lepton number violating process,
which produces sufficient lepton number asymmetry in the strong wash-out
regime. It helps to explain baryogenesis via the mechanism of thermal
leptogenesis. This model could also accommodate tiny neutrino masses and mixing
at one loop-level through the radiative seesaw mechanism.
Dilepton$+slashed{E}_T$ signature arising from the new fermionic sector can
observe at Large Hadron Collider (LHC), satisfying relic density, including
other theoretical and experimental bounds. We perform such analysis for a
benchmark point in the context of 14 TeV LHC experiments with a future
integrated luminosity of 3000 ${
m fb^{-1}}$. | | Source: | arXiv, 2001.4070 | | Services: | Forum | Review | PDF | Favorites | |
