CP transformed mixed antisymmetry for neutrinos and its consequences
Roopam Sinha, Probir Roy, Ambar Ghosal
We propose a complex extension of mixed antisymmetry in the neutrino Majorana mass matrix . This can be implemented in the Lagrangian by a generalized CP transformation (…
Consequences of minimal seesaw with complex antisymmetry of neutrinos
Rome Samanta, Probir Roy, Ambar Ghosal
We propose a complex extension of permutation antisymmetry in the neutrino Majorana matrix . The latter can be realized for the Lagrangian by appropriate CP transformatio…
Baryon asymmetry via leptogenesis in a neutrino mass model with complex scaling
Rome Samanta, Mainak Chakraborty, Probir Roy +1
Baryogenesis via leptogenesis is investigated in a specific model of light neutrino masses and mixing angles. The latter was proposed on the basis of an assumed complex-extended sc…
Complex Scaling in Neutrino Mass Matrix
Rome Samanta, Probir Roy, Ambar Ghosal
Using the residual symmetry approach, we propose a complex extension of the scaling ansatz on which allows a nonzero mass for each of the three light neutrinos as well as a n…
Extended scaling and residual flavor symmetry in the neutrino Majorana mass matrix
Rome Samanta, Probir Roy, Ambar Ghosal
The residual symmetry approach, along with a complex extension for some flavor invariance, is a powerful tool to uncover the flavor structure of the neutrino Majorana ma…
Dwarf Galaxy -excess and 3.55 keV X-ray Line In A Nonthermal Dark Matter Model
Anirban Biswas, Debasish Majumdar, Probir Roy
Recent data from Reticulum II (RetII) require the energy range of the FermiLAT -excess to be GeV. We adjust our unified nonthermal Dark Matter (DM) model to accomm…
