Scalar Triplet Leptogenesis with a CP violating phase
Sreerupa Chongdar, Sasmita Mishra
We study baryogenesis through leptogenesis via decay of triplet scalars embedded in the Standard Model. We consider two triplets scenario where the vacuum expectation value develop…
Neutrino mass observables and non-Hermitian version of Type-I seesaw model
Sasmita Mishra
We study the non-Hermitian extension of the Lagrangian of the Standard Model extended by singlet right-handed heavy neutrinos. The Yukawa coupling matrices comprise of hermitian an…
Threshold effects and renormalization group evolution of neutrino parameters in TeV scale seesaw models
Srubabati Goswami, Subrata Khan, Sasmita Mishra
We consider the threshold effect on the renormalization group (RG) evolution of the neutrino masses and mixing angles in TeV scale seesaw models. We obtain the analytic expressions…
Spontaneous R-parity breaking, Left-Right Symmetry and Consistent Cosmology with Transitory Domain Walls
Debasish Borah, Sasmita Mishra
Domain wall formation is quite generic in spontaneous Left-Right parity (D-parity) breaking models. Since they are in conflict with cosmology, we need some mechanisms to remove the…
Spontaneously broken parity and consistent cosmology with transitory domain walls
Sasmita Mishra, Urjit A. Yajnik
Domain wall structure which may form in theories with spontaneously broken parity is generically in conflict with standard cosmology. It has been argued that Planck scale suppresse…
Gauge mediated supersymmetry breaking and the cosmology of Left-Right symmetric model
Sasmita Mishra, Anjishnu Sarkar, Urjit A. Yajnik
Left-Right symmetry including supersymmetry presents an important class of gauge models which may possess natural solutions to many issues of phenomenology. Cosmology of such model…
