Search for Sterile Neutrinos by the MINOS Long-baseline Neutrino Experiment
Presented by Dr. ANDREW BLAKE on 22 Jul 2014 from 14:30 to 14:50
Type: Lepton Flavour Violation and Neutrinos
Track: Lepton Flavour Violation and Neutrinos
MINOS is a long-baseline neutrino oscillation experiment operated at the Fermi Laboratory, USA. The experiment is situated along the central axis of the NuMI accelerator neutrino beam, and comprises two kiloton-scale steel-scintillator detectors, located 1km and 735km downstream of the beam target. Since its start-up in 2005, the NuMI beam facility has delivered in excess of 15e20 protons-on-target, enabling MINOS to perform precision measurements of neutrino oscillations. MINOS is the only long-baseline experiment exposed to a wide-band accelerator beam and therefore able to measure neutrino oscillations over a broad range of energies. This enables MINOS to perform searches for new physics beyond the standard model of neutrino oscillations. In particular, MINOS is sensitive to sterile neutrinos in the regions of parameter space favoured by the LSND and MiniBooNE experiments. In this talk, I will present the latest sterile neutrino results from MINOS, based on a 3+1 model. I will also preview the sensitivity of the next phase of the experiment, MINOS+, which has recently begun operating in the higher-intensity and higher-energy NuMI beam.
