Title: Neutrino oscillations with MINOS and MINOS+

The MINOS experiment ran from 2003 until 2012 and collected a data sample including 10.71 x 10 20 protons-on-target (POT) of beam neutrinos, 3.36 x 10 20 POT of beam antineutrinos and an atmospheric neutrino exposure of 37.88 kt-yrs. The final measurement of the atmospheric neutrino oscillation parameters, Δm 2 32 and θ 23, came from a full three flavour oscillation analysis of the combined CCv μ and CCv¯ μ beam and atmospheric samples and the CCv e and CCv¯ e appearance samples. This analysis yielded the most precise measurement of the atmospheric mass splitting dm^2_32 performed to date. The results are |Δm 2 32| = [2.28 - 2.46] x 10 -3 eV 2 (68%) and sin 2θ 23 = 0.35-0.65 (90%) in the normal hierarchy, and |Δm 2 32| = [2.32 - 2.53]x10 -3 eV 2 (68%) and sin 2θ 23 = 0.34-0.67 (90%) in the inverted hierarchy. The successor to MINOS in the NO v A era at FNAL, MINOS+, is now collecting data mostly in the 3-10 GeV region, and an analysis of nu_mu disappearance using the first 2.99 x 10 20 POT of data produced results very consistent with those from MINOS. Here, future data willmore » further test the standard neutrino oscillation paradigm and allow for improved searches for exotic phenomena including sterile neutrinos, large extra dimensions and non-standard interactions.« less
