Neutrino Oscillations as an Open Quantum System in Strong Gravitational Fields: Spin-Connection Decoherence and Kerr Frame Dragging

Gayatri Ghosh

We investigate neutrino flavor evolution in strong gravitational fields within an open-quantum-system framework in curved spacetime. Starting from the Dirac equation in the vierbei…

Pseudo-Goldstone Neutrinos and Majoron Phenomenology from Spontaneous $U (1) L I^¼ - L_{I ¨} $ Breaking

Gayatri Ghosh

We present a predictive framework for neutrino mass generation based on the spontaneous breaking of a leptonic $U (1)_{L_{I^} ¼ - L_{I ¨} }$ symmetry within a supersymmetric setting. The brea…

Hybrid Type-I and Type-II Leptogenesis in Minimal Renormalizable $SO (10)$

Gayatri Ghosh

We investigate flavoured hybrid leptogenesis in a minimal renormalizable $SO (10)$ framework in which both Type-I and Type-II seesaw interactions contribute to the generati…

Radiative $I^¼ - I ¨ $ Corrections and Renormalization of Neutrino Mass Operators in Type II Seesaw Models

Gayatri Ghosh

We explore the impact of radiative $I^¼ - I ¨ $ corrections on the renormalization of neutrino mass operators in the Type II Seesaw framework, incorporating both dimension-five and dime…
