Description
We study the capability of the off-axis near detector ND280 of the T2K experiment to search for LLPs, and show constraints on the dark photon model and the B-L model. It is found that the ten-year operation of T2K with the ND280 detector excludes the unexplored parameter region of the models. We also show that a broader parameter region can be searched by the ND280 in the future T2K operation.
