Effect of sterile phases on degeneracy resolution capabilities of LBL experiments

Abstract

In sterile neutrino (3+1) parameterisation, we observe that sterile phases (${\delta }_{14},{\delta }_{24}$) are always together in oscillation probability, even when the MSW effect is considered. We see that the difference between the sterile phases has a more dominating effect over event rates compared to small variations due to changes in individual values. In this work, we show the value of sterile phase difference (${\delta }_{14}-{\delta }_{24}$) that least affects the parameter degeneracy resolution of ${\delta }_{13},{\theta }_{23}$ at long-baseline experiments.
