WIMP Dark Matter and Baryogenesis
Pei-Hong Gu, Manfred Lindner, Utpal Sarkar +1
In the present universe visible and dark matter contribute comparable energy density although they have different properties. This coincidence can be elegantly explained if the dar…
Experimental signatures of cosmological neutrino condensation
Mofazzal Azam, Jitesh R. Bhatt, Utpal Sarkar
Superfluid condensation of neutrinos of cosmological origin at a low enough temperature can provide simple and elegant solution to the problems of neutrino oscillations and the acc…
Leptogenesis with Linear, Inverse or Double Seesaw
Pei-Hong Gu, Utpal Sarkar
The left-right symmetric model with doublet and bi-doublet Higgs scalars can accommodate linear, inverse or double seesaw for generating small neutrino masses in the presence of th…
TeV scale Left Right Symmetry with spontaneous D-parity breaking
Debasish Borah, Sudhanwa Patra, Utpal Sarkar
The different scenarios of spontaneous breaking of D-parity have been studied in both non-supersymmetric and supersymmetric version of the left-right symmetric models(LRSM). We exp…
Pseudo-Majoron as Dark Matter
Pei-Hong Gu, Ernest Ma, Utpal Sarkar
We consider the singlet Majoron model with softly broken lepton number. This model contains three right-handed neutrinos and a singlet scalar besides the standard model fields. The…
Spontaneous Left-Right Symmetry Breaking in Supersymmetric Models with only Higgs Doublets
Sudhanwa Patra, Anjishnu Sarkar, Utpal Sarkar
We studied the question of parity breaking in a supersymmetric left-right model, in which the left-right symmetry is broken with Higgs doublets (carrying ). Unlike the l…
