Item Improved measurement of muon antineutrino disappearance in MINOS(American Physical Society, 2012) Adamson, P.; Ayres, D.S.; Backhouse, C.; Barr, G.; Bishai, M.; Blake, A.; Bock, G.J.; Boehnlein, D.J.; Bogert, D.; Cao, S.V.; Childress, S.; Coelho, J.A.B.; Corwin, L.; Cronin-Hennessy, D.; Danko, I.Z.; De Jong, J.K.; Devenish, N.E.; Diwan, M.V.; Escobar, C.O.; Evans, J.J.; Falk, E.; Feldman, G.J.; Frohne, M.V.; Gallagher, H.R.; Gomes, R.A.; Goodman, M.C.; Gouffon, P.; Graf, N.; Gran, R.; Grzelak, K.; Habig, A.; Hartnell, J.; Hatcher, R.; Himmel, A.; Holin, A.; Huang, X.; Hylen, J.; Irwin, G.M.; Isvan, Z.; Jaffe, D.E.; James, C.; Jensen, D.; Kafka, T.; Kasahara, S.M.S.; Koizumi, G.; Kopp, S.; Kordosky, M.; Kreymer, A.; Lang, K.; Ling, J.; Litchfield, P.J.; Loiacono, L.; Lucas, P.; Mann, W.A.; Marshak, M.L.; Mathis, M.; Mayer, N.; Mehdiyev, R.; Meier, J.R.; Messier, M.D.; Michael, D.G.; Miller, W.H.; Mishra, S.R.; Mitchell, J.; Moore, C.D.; Mualem, L.; Mufson, S.; Musser, J.; Naples, D.; Nelson, J.K.; Newman, H.B.; Nichol, R.J.; Nowak, J.A.; Oliver, W.P.; Orchanian, M.; Pahlka, R.B.; Paley, J.; Patterson, R.B.; Pawloski, G.; Phan-Budd, S.; Plunkett, R.K.; Qiu, X.; Radovic, A.; Ratchford, J.; Rebel, B.; Rosenfeld, C.; Rubin, H.A.; Sanchez, M.C.; Schneps, J.; Schreckenberger, A.; Schreiner, P.; Sharma, R.; Sousa, A.; Strait, M.; Tagg, N.; Talaga, R.L.; Thomas, J.; Thomson, M.A.; Tinti, G.; Toner, R.; Torretta, D.; Tzanakos, G.; Urheim, J.; Vahle, P.; Viren, B.; Walding, J.J.; Weber, A.; Webb, R.C.; White, C.; Whitehead, L.; Wojcicki, S.G.; Zwaska, R.We report an improved measurement of $\overline{\nu}_μ$ disappearance over a distance of 735 km using the MINOS detectors and the Fermilab Main Injector neutrino beam in a $\overline{\nu}_μ$-enhanced configuration. From a total exposure of $2.95×10^{20}$ protons on target, of which 42% have not been previously analyzed, we make the most precise measurement of $Δ\overline{m}^2=[2.62^{+0.31}_{−0.28}(\text{stat})±0.09(/text{syst})]×10^{−3} eV^2$ and constrain the $\overline{\nu}_μ$ mixing angle $sin^2(2\bar θ)>0.75$ (90% C.L.). These values are in agreement with $Δm^2$ and $sin^2(2θ)$ measured for $\nu_μ$, removing the tension reported in [P. Adamson et al. (MINOS), Phys. Rev. Lett. 107, 021801 (2011).].Item Search for Lorentz invariance and CPT violation with muon antineutrinos in the MINOS Near Detector(American Physical Society, 2012) Adamson, P.; Ayres, D.S.; Barr, G.; Bishai, M.; Blake, A.; Bock, G.J.; Boehnlein, D.J.; Bogert, D.; Cao, S.V.; Cavanaugh, S.; Childress, S.; Coelho, J.A.B.; Corwin, L.; Cronin-Hennessy, D.; Danko, I.Z.; De Jong, J.K.; Devenish, N.E.; Diwan, M.V.; Escobar, C.O.; Evans, J.J.; Falk, E.; Feldman, G.J.; Frohne, M.V.; Gallagher, H.R.; Gomes, R.A.; Goodman, M.C.; Gouffon, P.; Graf, N.; Gran, R.; Grzelak, K.; Habig, A.; Hartnell, J.; Hatcher, R.; Himmel, A.; Holin, A.; Hylen, J.; Irwin, G.M.; Isvan, Z.; James, C.; Jensen, D.; Kafka, T.; Kasahara, S.M.S.; Koizumi, G.; Kopp, S.; Kordosky, M.; Kreymer, A.; Lang, K.; Ling, J.; Litchfield, P.J.; Loiacono, L.; Lucas, P.; Mann, W.A.; Marshak, M.L.; Mathis, M.; Mayer, N.; Mehdiyev, R.; Meier, J.R.; Messier, M.D.; Miller, W.H.; Mishra, S.R.; Mitchell, J.; Moore, C.D.; Mualem, L.; Mufson, S.; Musser, J.; Naples, D.; Nelson, J.K.; Newman, H.B.; Nichol, R.J.; Nowak, J.A.; Oliver, W.P.; Orchanian, M.; Pahlka, R.B.; Paley, J.; Patterson, R.B.; Pawloski, G.; Phan-Budd, S.; Plunkett, R.K.; Qiu, X.; Radovic, A.; Ratchford, J.; Rebel, B.; Rosenfeld, C.; Rubin, H.A.; Sanchez, M.C.; Schneps, J.; Schreckenberger, A.; Schreiner, P.; Sharma, R.; Sousa, A.; Strait, M.; Tagg, N.; Talaga, R.L.; Thomas, J.; Thomson, M.A.; Tinti, G.; Toner, R.; Torretta, D.; Tzanakos, G.; Urheim, J.; Vahle, P.; Viren, B.; Walding, J.J.; Weber, A.; Webb, R.C.; White, C.; Whitehead, L.; Wojcicki, S.G.; Zwaska, R.We have searched for sidereal variations in the rate of antineutrino interactions in the MINOS Near Detector. Using antineutrinos produced by the NuMI beam, we find no statistically significant sidereal modulation in the rate. When this result is placed in the context of the Standard Model Extension theory we are able to place upper limits on the coefficients defining the theory. These limits are used in combination with the results from an earlier analysis of MINOS neutrino data to further constrain the coefficients.
