Description
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($\delta_{14}-\delta_{24}$), least effects the parameter degeneracy resolution of $\delta_{13},\theta_{23}$ at NOvA. We find the value of sterile phase difference that will give a greater chance at sterile neutrino discovery.
