Influence of multi-Higgs doublet in scalar and fermionic sector within minimal extended seesaw framework | | Pritam Das

17 Nov 2019 | | Abstract: | We study a model of neutrino and dark matter within the framework of minimal
extended seesaw. This framework is based on $A_4$ flavor symmetry along with
the discrete $Z_4$ symmetry to stabilize the dark matter and construct desired
mass matrices for neutrino mass. We use non-trivial Dirac mass matrix with
broken $mu- au$ symmetry to generate the leptonic mixing and consider a
non-degenerate mass structure for right-handed neutrinos to verify the observed
baryon asymmetry of the Universe via the mechanism of thermal Leptogenesis.
Scalar sector is also studied in great details for multi Higgs doublet
scenario, considering the lightest $Z_4$-odd as a viable dark matter candidate.
A significant impact on the region of DM parameter space as well as in the
fermionic sector are found in the presence of extra scalar particles. | | Source: | arXiv, 1911.7243 | | Services: | Forum | Review | PDF | Favorites | |
