Abstract
The T2K experiment has performed a search for disappearance due to sterile neutrinos using protons on target for a baseline of 280 m in a neutrino beam peaked at about 500 MeV. A sample of CC interactions in the off-axis near detector has been selected with a purity of 63% and an efficiency of 26%. The p-value for the null hypothesis is 0.085 and the excluded region at 95% C.L. is approximately for .
