First measurement of the muon neutrino charged current single pion production cross section on water with the T2K near detector
Physical Review D American Physical Society 95:1 (2017)
Abstract:
The T2K off-axis near detector, ND280, is used to make the first differential cross section measurements of muon neutrino charged current single positive pion production on a water target at energies ∼0.8 GeV. The differential measurements are presented as a function of the muon and pion kinematics, in the restricted phase space defined by pπ+>200 MeV/c, pμ>200 MeV/c, cos(θπ+)>0.3 and cos(θμ)>0.3. The total flux integrated νμ charged current single positive pion production cross section on water in the restricted phase space is measured to be σSearch for flavor-changing nonstandard neutrino interactions using νe appearance in MINOS

Abstract:
We report new constraints on flavor-changing nonstandard neutrino interactions from the MINOS long-baseline experiment using νe and νe appearance candidate events from predominantly νμ and νμ beams. We used a statistical selection algorithm to separate νe candidates from background events, enabling an analysis of the combined MINOS neutrino and antineutrino data. We observe no deviations from standard neutrino mixing, and thus place constraints on the nonstandard interaction matter effect, | μeτ|, and phase, (δCP+δeτ), using a 30-bin likelihood fit.Measuring neutrino-induced exclusive charge-current final states on hydrogen at T2K

Constraints on large extra dimensions from the MINOS experiment
Physical Review D American Physical Society 94:11 (2016) 111101(R)
Abstract:
We report new constraints on the size of large extra dimensions from data collected by the MINOS experiment between 2005 and 2012. Our analysis employs a model in which sterile neutrinos arise as Kaluza-Klein states in large extra dimensions and thus modify the neutrino oscillation probabilities due to mixing between active and sterile neutrino states. Using Fermilab's Neutrinos at the Main Injector beam exposure of 10.56×1020 protons on target, we combine muon neutrino charged current and neutral current data sets from the Near and Far Detectors and observe no evidence for deviations from standard three-flavor neutrino oscillations. The ratios of reconstructed energy spectra in the two detectors constrain the size of large extra dimensions to be smaller than 0.45 μm at 90% C.L. in the limit of a vanishing lightest active neutrino mass. Stronger limits are obtained for nonvanishing masses.Measurement of coherent π^{+} production in low energy neutrino-carbon scattering
