The sensitivity of MINOS+ to the existence of sterile neutrinos, when combined with data from the Bugey [85] reactor neutrino experiment. is the splitting between the three known neutrino mass states and a new, fourth state. is the mixing angle governing transitions when a fourth, sterile neutrino state is introduced into the PMNS mixing matrix. This figure assumes two years of MINOS+ running with a neutrino-dominated beam.
