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 density …

Discrete symmetries being preferred to explain the neutrino phenomenology, we chose the
simplest $ S_3 $ group and explore the implication of its modular form on neutrino masses …

Motivated by the fact that δ CP, the Dirac phase in the PMNS matrix, is the only CP-violating
parameter in the leptonic sector that can be measured in neutrino oscillation experiments …

A bstract We use S 4 discrete group to construct a neutrino flavour model which leads to TM
1 mixing and is consistent with the neutrino oscillation data. Using the model's constrained …

A bstract We propose a minimal A 4 flavor symmetric model, assisted by Z 2× Z 3 symmetry,
which can naturally takes care of the appropriate lepton mixing and neutrino masses via …

In a pure inverse seesaw framework, achieving a substantial lepton asymmetry that can be
converted into the observed baryon asymmetry of the Universe is extremely challenging …

A bstract Within the framework of residual symmetry, two ℤ 2 type associate μτ inter-change
symmetries robustly constrain the Dirac CP phase δ in a model independent way. Both of …

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 …

A bstract We investigate the consequences of a generalized ℤ 2× ℤ 2 symmetry on a scaling
neutrino Majorana mass matrix. It enables us to determine definite analytical relations …

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 …
