Results from the MINOS Experiment and New MINOS+ Data

Abstract

The MINOS experiment took data for seven years between May 2005 and April 2012. Since then it has been reborn as the new MINOS+ experiment in the upgraded medium energy NuMI beam and started taking data in September 2013. An update to the MINOS standard oscillations three-flavour disappearance analysis is presented which includes 28% more atmospheric neutrino data. This combined three-flavour analysis calculates an atmospheric parameter best-fit point of Δm322=2.370.07+0.11×103\Delta m_{32}^{2}=2.37^{+0.11}_{-0.07} \times 10^{-3}~eV2^{2} and sin2θ23=0.430.05+0.19\sin^{2}\theta_{23}=0.43^{+0.19}_{-0.05} for the inverted hierarchy, for which the MINOS fit shows a slight preference. A first look at the new MINOS+ beam data is presented. The new data is consistent with the combined three-flavour analysis. Finally, new MINOS results for the search for sterile neutrinos using neutrino disappearance are shown which cut out a significant amount of the allowed phase space for a sterile neutrino to exist.
