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 ($…
Enhancing the sensitivity to neutrino oscillation parameters using synergy between T2K, NOA and JUNO
Srubabati Goswami, Aman Gupta, Ushak Rahaman +1
We study the impact of combining the present NOA and T2K data with simulated data from the JUNO experiment on the determination of the leptonic CP phase and the neutrino mass h…
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…
Universal Seesaw Leptogenesis
K. S. Babu, Maximilian Berbig, Srubabati Goswami +1
We study the implications for leptogenesis in a class of left-right symmetric model, where all fermion masses are induced through the Universal Seesaw mechanism. Unlike conventiona…
Probing Geometrical NSI at the DUNE experiment
Riya Barick, Indrajit Ghose, Srubabati Goswami +2
In this work, we investigate the implications of a novel non-standard interaction (NSI) of neutrinos. This interaction is geometric in origin -- it arises because the propagation o…
Testing residual-symmetry-fixed columns of at DUNE and T2HK with initial JUNO constraints
Debajyoti Dutta, Srubabati Goswami, Monal Kashav +1
We study fixed-column predictions of the lepton mixing matrix that arise from residual symmetries originating in a class of discrete flavour and modular symmetries. While the recen…
