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…
Torsional modulation of atmospheric neutrino oscillation
Riya Barick, Amitabha Lahiri
Fermions act as sources of spacetime torsion. However, this torsion is non-dynamical and can be eliminated using its equations of motion. The resulting theory features an effective…
Neutrino Oscillation in Core Collapse Supernova: The Impact of Spacetime Geometry
Indrajit Ghose, Amitabha Lahiri
Neutrino flavor evolution inside a core-collapse supernova is a topic of active research. The core of a supernova is an intense source of neutrinos and antineutrinos. Self-interact…
Exploring the Effect of Chiral Torsion on Neutrino Oscillation in Long Baseline Experiments
Riya Barick, Amitabha Lahiri
In curved spacetime, neutrinos experience an extra contribution to their effective Hamiltonian coming from a torsion-induced four-fermion interaction that is diagonal in mass basis…
Effects of spacetime geometry on neutrino oscillation inside a Core-Collapse Supernova
Indrajit Ghose, Amitabha Lahiri
Neutrinos are excellent probes of the inner structures of supernovas. However, an understanding of their dynamics remains incomplete, which is crucial for properly interpreting the…
