“…The calorimeter section records the energy deposited by neutrino-induced hadronic showers. For the sub-GeV hadronic showers of interest to this analysis, the resolution for calorimetric measurement of hadronic shower energy is approximately 80% [38,39]. The downstream spectrometer section provides the curvature and range information required for reconstructing the momenta of muons from CC interactions in the calorimeter.…”

Study of quasielastic scattering using charged-current ν_{μ}-iron interactions in the MINOS near detector Kinematic distributions from an inclusive sample of 1.41 × 10 6 charged-current νµ interactions on iron, obtained using the MINOS Near Detector exposed to a wide-band beam with peak flux at 3 GeV, are compared to a conventional treatment of neutrino scattering within a Fermi gas nucleus. Results are used to guide the selection of a subsample enriched in quasielastic νµFe interactions, containing an estimated 123,000 quasielastic events of incident energies 1 < Eν < 8 GeV, with Eν = 2.79 GeV. Four additional subsamples representing topological and kinematic sideband regions to quasielastic scattering are also selected for the purpose of evaluating backgrounds. Comparisons using subsample distributions in four-momentum transfer Q 2 show the Monte Carlo model to be inadequate at low Q 2 . Its shortcomings are remedied via inclusion of a Q 2 -dependent suppression 2 function for baryon resonance production, developed from the data. A chi-square fit of the resulting Monte Carlo simulation to the shape of the Q 2 distribution for the quasielastic-enriched sample is carried out with the axial-vector mass MA of the dipole axial-vector form factor of the neutron as a free parameter. The effective MA which best describes the data is 1.23 +0.13 −0.09 (fit) +0.12 −0.15 (syst.) GeV.

“…At the NuFact09 workshop session where these results were presented, there was excellent discussion, especially contributions by Arie Bodek. The MINOS portion of this paper is naturally similar to (but more brief than) the proceedings paper on the same topic written by Mark Dorman for NuInt09 [7].…”

“…These proceedings describes a preliminary result from an analysis of the shape of the Q 2 spectrum for a QE one-track sample based on the Run-I data set, which is about 1/6 of the total accumulated data. Another, longer description of this result is available in the NuInt09 proceedings [7], which contains many more details about the analysis than will fit in this paper.…”

Abstract. In these proceedings, I describe the status of quasielastic cross section measurements at energies of a few GeV. The main new measurements discussed here are an absolute cross section and also a Q 2 shape measurement by NOMAD, which has recently been published, and a preliminary Q 2 shape measurement by the MINOS collaboration. The NOMAD detector has good statistics and very good reconstruction of the recoil proton. The MINOS detector has enormous statistics, and makes measurements on iron, not carbon, but is using a sample that specifically has very low hadronic energy (one-track sample) and no reconstructable proton. From the discussions at NuFact09 and elsewhere, I compare these measurements with other recent results at lower energy.

A measurement of neutrino oscillations with muon neutrinos in the MINOS experiment

PAGEExperimental evidence has established that neutrino flavor states evolve over time. A neutrino of a particular flavor that travels some distance can be detected in a different neutrino flavor state. The Main Injector Neutrino Oscillation Search (MINOS) is a long-baseline experiment that is designed to study this phenomenon, called neutrino oscillations. MI-NOS is based at Fermilab near Chicago, IL, and consists of two detectors: the Near Detector located at Fermilab, and the Far Detector, which is located in an old iron mine in Soudan, MN. Both detectors are exposed to a beam of muon neutrinos from the NuMI beamline, and MINOS measures the fraction of muon neutrinos that disappear after traveling the 734 km between the two detectors. One can measure the atmospheric neutrino mass splitting and mixing angle by observing the energy-dependence of this muon neutrino disappearance. MINOS has made several prior measurements of these parameters.Here I describe recently-developed techniques used to enhance our sensitivity to the oscillation parameters, and I present the results obtained when they are applied to a dataset that is twice as large as has been previously analyzed. We measure the mass splitting ∆m These results comprise the world's best measurement of the atmospheric neutrino mass splitting. Alternative disappearance models are also tested. The neutrino decay hypothesis is disfavored at 7.2σ and the neutrino quantum decoherence hypothesis is disfavored at 9.0σ.
