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…
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…
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…
