The Daya Bay and T2K results on ${\sin }^{2}2{\theta }_{13}$ and Non-Standard Neutrino Interactions

Abstract

We show that the relatively large best fit value of ${\sin }^{2}2{\theta }_{13}=0.14(0.17)$ measured in the T2K experiment for fixed values of i) the Dirac CP violation phase $\delta =0$, and ii) the atmospheric neutrino mixing parameters ${\theta }_{23}=\pi /4$, $|\Delta m_{32}^2|=2.4\times 10^{-3}{\mathrm{eV}}^2$, can be reconciled with the Daya Bay result ${\sin }^{2}2{\theta }_{13}=0.090\pm 0.009$ if the effects of non-standard neutrino interactions (NSI) in the relevant ${\bar{\nu }}_e\to {\bar{\nu }}_e$ and ${\nu }_{\mu }\to {\nu }_e$ oscillation probabilities are taken into account.
