Velocity Induced Neutrino Oscillation and its Possible Implications for Long Baseline Neutrinos

TL;DR

This paper explores how differences in maximum attainable velocities of neutrinos could induce additional flavor oscillations, impacting long baseline neutrino experiments and potentially revealing new physics beyond the standard mass-induced oscillations.

Contribution

It introduces a novel velocity-induced neutrino oscillation mechanism considering matter effects and analyzes its implications for long baseline neutrino experiments.

Findings

Velocity differences can cause additional flavor oscillations.

Matter effects modify the velocity-induced oscillation signatures.

Predicted experimental signatures could help identify velocity-induced oscillations.

Abstract

If the three types of active neutrinos possess different maximum attainable velocities and the neutrino eigenstates in the velocity basis are different from those in the flavour (and mass) basis then this will induce a flavour oscillation in addition to the normal mass flavour oscillation. Here we study such an oscillation scenario in three neutrino framework including also the matter effect and apply our results to demonstrate its consequences for long baseline neutrinos. We also predict the possible signatures in terms of yields in a possible long baseline neutrino experiment.
