Sensitivity of T2KK to the non-standard interaction in propagation

Abstract

Assuming only the non-zero electron and tau neutrino components ${\epsilon }_{ee}$, ${\epsilon }_{e\tau }$, ${\epsilon }_{\tau \tau }$ of the non-standard matter effect and postulating the atmospheric neutrino constraint ${\epsilon }_{\tau \tau }=|{\epsilon }_{e\tau }{|}^2/(1+{\epsilon }_{ee})$, we study the sensitivity to the non-standard interaction in neutrino propagation of the T2KK neutrino long-baseline experiment. It is shown that T2KK can constrain the parameters $|{\epsilon }_{ee}|\lesssim 1$, $|{\epsilon }_{e\tau }|\lesssim 0.2$. It is also shown that if $|{\epsilon }_{e\tau }|$ and ${\theta }_{13}$ are large, then T2KK can determine the Dirac phase and the phase of ${\epsilon }_{e\tau }$ separately, due to the information at the two baselines. We also provide an argument that the components $|{\epsilon }_{\alpha \mu }|$ $(\alpha =e,\mu ,\tau )$ must be small for the disappearance oscillation probability to be consistent with high-energy atmospheric neutrino data, which justifies our premise that these quantities are negligible.
