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…
Spontaneous parity breaking with broken supersymmetry : cosmological constraint
Urjit A. Yajnik, Sasmita Mishra, Debasish Borah
Unified models incorporating the right handed neutrino in a symmetric way generically possess parity symmetry. If this is broken spontaneously it results in the formation of domain…
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…
Supersymmetry Breaking and Dilaton Stabilization in String Gas Cosmology
Sasmita Mishra, Wei Xue, Robert Brandenberger +1
In this Note we study supersymmetry breaking via gaugino condensation in string gas cosmology. We show that the same gaugino condensate which is introduced to stabilize the dilaton…
