Torsional four-fermion interaction for Majorana neutrinos
Indrajit Ghose, Amitabha Lahiri
Fermions generate spacetime torsion, which can be eliminated, leaving behind an effective four-fermion interaction. This term will contribute an effective mass for neutrinos propag…
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…
Effect of spacetime geometry on neutrino oscillations
Riya Barick, Indrajit Ghose, Amitabha Lahiri
Propagation of fermions in spacetime requires a spin connection, which can be split into a universal gravitational part and a non-universal ``contorsion'' part. The latter is non-d…
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…
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…
