Search for short baseline νe disappearance with the T2K near detector

Published

Journal Article

© 2015 American Physical Society. The T2K experiment has performed a search for νe disappearance due to sterile neutrinos using 5.9×1020 protons on target for a baseline of 280 m in a neutrino beam peaked at about 500 MeV. A sample of νe 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 sin22θee>0.3 for Δmeff2>7eV2/c4.
