Thermal Leptogenesis in the BNT Model of Neutrino Mass
P. S. Bhupal Dev, Srubabati Goswami, Debashis Pachhar +1
We investigate neutrino mass and thermal leptogenesis in the Babu-Nandi-Tavartkiladze (BNT) model featuring a scalar quadruplet () and a pair of vector-like fermion triplets ($Σ…
Neutrino mass variables in 3 active and 2 sterile neutrino scenario
Srubabati Goswami, Hemanth M., Debashis Pachhar +1
The three-flavor framework of neutrino oscillations successfully explains most experimental results, but persistent anomalies at short- and long-baseline experiments hint at the ex…
Scalar-induced Neutrinoless Double Beta Decay in
P. S. Bhupal Dev, Srubabati Goswami, Debashis Pachhar +1
We discuss the role of heavy scalar fields in mediating neutrinoless double beta decay within the Grand Unified Theory framework, extended suitably to include neut…
Neutrinoless Double Beta Decay from Scalar Leptoquarks: Interplay with Neutrino Mass and Flavor Physics
P. S. Bhupal Dev, Srubabati Goswami, Chayan Majumdar +1
We perform a comprehensive analysis of neutrinoless double beta decay and its interplay with low-energy flavor observables in a radiative neutrino mass model with scalar leptoquark…
Constraining the mass-spectra in the presence of a light sterile neutrino from absolute mass-related observables
Srubabati Goswami, Debashis Pachhar, Supriya Pan
The framework of three-flavor neutrino oscillation is a well-established phenomenon, but results from the short-baseline experiments, such as the Liquid Scintillator Neutrino Detec…
