The MINOS and MINOS+ experiments collected accelerator beam neutrino and antineutrino data for 11 years corresponding to peak energies of 3 GeV and 6 GeV, respectively, over a baseline of 735 km. These proceedings report on new limits and constraints set by MINOS and MINOS+ in and beyond the standard three-flavor paradigm. The atmospheric neutrino mass splitting in the three-flavor model is measured to be (2.42 ± 0.09) × 10 −3 eV 2 for normal mass ordering and −(2.48 +0.09 −0.11 ) × 10 −3 eV 2

Constraints are set on sterile neutrinos and antineutrinos in the four-flavor model by looking for sterile-driven νµ and νµ disappearance and sterile-driven νe and νe appearance. A combination of the MINOS fourflavor νµ disappearance search and the Daya Bay and Bugey-3 four-flavor νe disappearance searches excludes the parameter space allowed by LSND and MiniBooNE for ∆m 2 41 < 0.8 eV 2 at 90% C.L. The size of large extra dimensions is constrained to be smaller than 0.17 µm at 90% C.L. in the limit of a vanishing lightest active neutrino mass. Finally, a search for non-standard ν e and νe appearance in MINOS is presented.
