Baryon asymmetry and lower bound on right handed neutrino mass in fast expanding Universe: an analytical approach
Mainak Chakraborty, Sourov Roy
The expansion rate of the Universe deviates from its standard value when the total energy density includes contribution from a new scalar field apart from the radiation energy dens…
Purely Triplet Seesaw and Leptogenesis within Cosmological Bound, Dark Matter and Vacuum Stability
Mina Ketan Parida, Mainak Chakraborty, Swaraj Kumar Nanda +1
In a novel standard model extension it has been suggested that, even in the absence of right-handed neutrinos and type-I seesaw, purely triplet leptogenesis leading to baryon asymm…
Predictive flavon model with mixing and baryogenesis through leptogenesis
Mainak Chakraborty, R. Krishnan, Ambar Ghosal
We use discrete group to construct a neutrino flavour model which leads to mixing and is consistent with the neutrino oscillation data. Using the model's constrained p…
Triplet Leptogenesis, Type-II Seesaw Dominance, Intrinsic Dark Matter, Vacuum Stability and Proton Decay in Minimal SO(10) Breakings
Mainak Chakraborty, M. K. Parida, Biswonath Sahoo
We implement type-II seesaw dominance for neutrino mass and baryogenesis through heavy scalar triplet leptogenesis in a class of minimal non-supersymmetric SO(10) models where matt…
Neutrino Mass, Coupling Unification, Verifiable Proton Decay, Vacuum Stability and WIMP Dark Matter in SU(5)
Biswonath Sahoo, Mainak Chakraborty, M. K. Parida
Nonsupersymmetric minimal SU(5) with Higgs representations and and standard fermions in is well known for its failure in unification of gau…
Matter Parity Violating Dark Matter Decay in Minimal SO(10), Unification, Vacuum Stability and Verifiable Proton Decay
Biswonath Sahoo, M. K Parida, Mainak Chakraborty
In direct breaking of non-supersymmetric SO(10) to the standard model, we investigate the possibility that dark matter (DM) decaying through its mixing with right-handed neutrino (…
Modified TBM and role of a hidden
Rome Samanta, Mainak Chakraborty
In a residual symmetry approach, we investigate minimally perturbed Majorana neutrino mass matrices. Constraint relations among the low energy ne…
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…
Evaluation of the Majorana Phases of a General Majorana Neutrino Mass Matrix: Testability of hierarchical Flavour Models
Rome Samanta, Mainak Chakraborty, Ambar Ghosal
We evaluate the Majorana phases for a general complex symmetric neutrino mass matrix on the basis of Mohapatra-Rodejohann's phase convention using the three rephasing in…
Scaling ansatz with texture zeros in linear seesaw
Mainak Chakraborty, H. Zeen Devi, Ambar Ghosal
We investigate scaling ansatz with texture zeros within the framework of linear seesaw mechanism. In this variant of seesaw mechanism a simplified expression of effective neutrino…
Flavored leptogenesis with quasi degenerate neutrinos in a broken cyclic symmetric model
Biswajit Adhikary, Mainak Chakraborty, Ambar Ghosal
Cyclic symmetry in the neutrino sector with the type-I seesaw mechanism in the mass basis of charged leptons and right chiral neutrinos (, ) generates two fold deg…
Masses, mixing angles and phases of general Majorana neutrino mass matrix
Biswajit Adhikary, Mainak Chakraborty, Ambar Ghosal
General Majorana neutrino mass matrix is complex symmetric and for three generations of neutrinos it contains 12 real parameters. We diagonalize this general neutrino mass matrix a…
Scaling ansatz, four zero Yukawa textures and large
Biswajit Adhikary, Mainak Chakraborty, Ambar Ghosal
We investigate 'Scaling ansatz' in the neutrino sector within the framework of type I seesaw mechanism with diagonal charged lepton and right handed Majorana neutrino mass matrices…
