Title: Neutrino oscillations with MINOS and MINOS+

Journal Article · · Nuclear Physics. B

The MINOS experiment ran from 2003 until 2012 and collected a data sample including 10.71 x 1020 protons-on-target (POT) of beam neutrinos, 3.36 x 1020 POT of beam antineutrinos and an atmospheric neutrino exposure of 37.88 kt-yrs. The final measurement of the atmospheric neutrino oscillation parameters, Δm232 and θ23, came from a full three flavour oscillation analysis of the combined CCvμ and CCv¯μ beam and atmospheric samples and the CCve 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 |Δm232| = [2.28 - 2.46] x 10-3 eV2 (68%) and sin2θ23 = 0.35-0.65 (90%) in the normal hierarchy, and |Δm232| = [2.32 - 2.53]x10-3 eV2 (68%) and sin2θ23 = 0.34-0.67 (90%) in the inverted hierarchy. The successor to MINOS in the NOv 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 1020 POT of data produced results very consistent with those from MINOS. Here, future data will 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.
