Interactions and oscillations of coherent flavor eigenstates in beta decay

Abstract

The theory pioneered by Blasone and Vitiello describes massive neutrinos as generalized coherent flavor eigenstates within the extended Standard Model. In this paper, we compute the neutron beta decay spectrum for the Blasone-Vitiello theory in a model with two neutrinos. For relativistic neutrinos, the obtained spectrum is in agreement with the Standard Model. However, there are discrepancies when the kinetic energy of the electron is close to the end point energy. The possibility of measuring the discrepancies in future experiments is discussed.
