Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS + collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ μ e mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δ m 2 41 , excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL s for Δ m 2 41 < 13 eV 2 . Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL s for Δ m 2 41 < 1.6 eV 2 .
