Title: Dirac neutrino mass from the beta-decay end point modified by the dynamics of a Lorentz-violating equation of motion
Author: Bernardini, AE
Abstract: Using a generalized procedure for obtaining the equation of motion of a propagating fermionic particle, we examine previous claims for a lightlike preferred axis embedded in the framework of Lorentz-invariance violation with preserved algebra. In a high energy scale, the corresponding equation of motion is reduced to a conserving lepton number chiral (very special relativity) equation, and in a low energy scale, the Dirac equation for a free particle is recovered. The new dynamics introduces some novel ingredients (modified cross section) to the phenomenology of the tritium beta-decay end point.
