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_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.
大亚湾和MINOS+合作组开展了由惰性中微子混合驱动的电子反中微子、μ子中微子和μ子反中微子消失的搜索。本信函展示了这些搜索的综合结果，以及布热伊3号反应堆实验的排除结果，这些结果置于一个最小扩展的四中微子模型框架内。得出了对θ_{μe}混合角的显著改进的限制，这在质量平方差Δm_{41}^{2}的五个数量级上构成了迄今为止最严格的限制，在90%置信水平下排除了LSND和MiniBooNE观测所允许的90%置信水平的惰性中微子参数空间，对于Δm_{41}^{2}<13 eV^{2}。此外，对于Δm_{41}^{2}<1.6 eV^{2}，在99%置信水平下排除了LSND和MiniBooNE 99%置信水平允许的区域。
