New Results from the MINOS Experiment - EPS 2011 conference proceedings
The MINOS experiment is a long-baseline neutrino experiment designed to study neutrino behavior, in particular the phenomenon of neutrino oscillations. MINOS sends the NuMI neutrino beam through two detectors, a Near Detector 1 km downstream from the beam source at Fermilab, and a Far Detector 735 km away in the Soudan Mine in Minnesota. MINOS has been taking beam data since 2005. This document summarizes recent neutrino oscillations results, with particular emphasis on electron neutrino appearance, which probes the angle {delta}{sub 13} of the neutrino mass mixing matrix. For an exposure of 8.2 x 10{sup 20} protons on target, MINOS finds that sin{sup 2}(2{theta}{sub 13}) < 0.12 for the normal mass hierarchy, and < 0.20 for the inverted mass hierarchy at the 90% C.L., if the CP-violating phase {delta} = 0.
