Latest Results from MINOS and MINOS+
- Univ. of Texas, Austin, TX (United States). Dept. of Physics
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 eV2 for normal mass ordering and $$-({2.48}_{-0.11}^{+0.09})\times {10}^{-3}{\ {\rm{eV}}}^{2}$$ for inverted mass ordering. Constraints are set on sterile neutrinos and antineutrinos in the four-flavor model by looking for sterile-driven νμ and $${\bar{\nu }}_{{\rm{\mu }}}$$ disappearance and sterile-driven νe and $${\bar{\nu }}_{{\rm{e}}}$$ appearance. A combination of the MINOS four-flavor νμ disappearance search and the Daya Bay and Bugey-3 four-flavor $${\bar{\nu }}_{{\rm{e}}}$$ disappearance searches excludes the parameter space allowed by LSND and MiniBooNE for $${\rm{\Delta }}{m}_{41}^{2}\lt 0.8{\ {\rm{eV}}}^{2}$$ 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. In conclusion, a search for non-standard νe and $${\bar{\nu }}_{{\rm{e}}}$$ appearance in MINOS is presented.
