Abstract

This paper reports results from a search for νμ→ν e transitions by the MINOS experiment based on a 7×1020 protons-on-target exposure. Our observation of 54 candidate νe events in the far detector with a background of 49.1±7.0(stat)±2. 7(syst) events predicted by the measurements in the near detector requires 2 sin2(2θ13)sin2θ23<0. 12(0.20) at the 90% C.L. for the normal (inverted) mass hierarchy at δCP=0. The experiment sets the tightest limits to date on the value of θ13 for nearly all values of δCP for the normal neutrino mass hierarchy and maximal sin2(2θ 23).
