SUMMARY:Search for Sterile Neutrinos in MINOS and MINOS+ Using a Two-Detec

DESCRIPTION:A search for mixing between active neutrinos and light sterile
  neutrinos has been performed by looking for muon neutrino disappearance i
 n two detectors at baselines of 1.04 and 735 km\, using a combined MINOS a
 nd MINOS+ exposure of 16.36 × 10^20^ protons on target. A simultaneous fi
 t to the charged-current muon neutrino and neutral-current neutrino energy
  spectra in the two detectors yields no evidence for sterile neutrino mixi
 ng using a 3+1 model. The most stringent limit to date is set on the mixin
 g parameter sin^2^(θ_24) for most values of the sterile neutrino mass spl
 itting Δm^2^_41 > 10^−4^  eV^2^.
