A search for muon neutrino and antineutrino disappearance in MiniBooNE
The MiniBooNE Collaboration reports a search for \numu and \numubar
disappearance in the \dmsq region of a few \evsq. These measurements are
important for constraining models with extra types of neutrinos, extra
dimensions an d CPT violation. Fits to the shape of the \numu and \numubar
energy spectra reveal no evidence for disappearance at 90% confidence level
(CL) in either mode. This is the first test of \numubar disappearance between
\dmsq=0.1-10\evsq.Comment: 10 pages, 3 figures, submitted to PR
The MiniBooNE Detector
The MiniBooNE neutrino detector was designed and built to look for
muon-neutrino to electron-neutrino oscillations in the mixing parameter space
region where the LSND experiment reported a signal. The MiniBooNE experiment
used a beam energy and baseline that were an order of magnitude larger than
those of LSND so that the backgrounds and systematic errors would be completely
different. This paper provides a detailed description of the design, function,
and performance of the MiniBooNE detector.Comment: 46 pages, 21 figure
Physics at a future neutrino factory and super-beam facility
The conclusions of the Physics Working Group of the International Scoping Study of a future Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried out by the international community between NuFact05, (the 7th International Workshop on Neutrino Factories and Super-beams, Laboratori Nazionali di Frascati, Rome, 21-26 June 2005) and NuFact06 (Ivine, CA, 24-30 August 2006). The physics case for an extensive experimental programme to understand the properties of the neutrino is presented and the role of high-precision measurements of neutrino oscillations within this programme is discussed in detail. The performance of second-generation super-beam experiments, beta-beam facilities and the Neutrino Factory are evaluated and a quantitative comparison of the discovery potential of the three classes of facility is presented. High-precision studies of the properties of the muon are complementary to the study of neutrino oscillations. The Neutrino Factory has the potential to provide extremely intense muon beams and the physics potential of such beams is discussed in the final section of the report
The Neutrino Flux prediction at MiniBooNE
The Booster Neutrino Experiment (MiniBooNE) searches for numu-to-nue
oscillations using the O(1 GeV) neutrino beam produced by the Booster
synchrotron at the Fermi National Accelerator Laboratory (FNAL). The Booster
delivers protons with 8 GeV kinetic energy (8.89 GeV/c momentum) to a beryllium
target, producing neutrinos from the decay of secondary particles in the beam
line. We describe the Monte Carlo simulation methods used to estimate the flux
of neutrinos from the beamline incident on the MiniBooNE detector for both
polarities of the focussing horn. The simulation uses the Geant4 framework for
propagating particles, accounting for electromagnetic processes and hadronic
interactions in the beamline materials, as well as the decay of particles. The
absolute double differential cross sections of pion and kaon production in the
simulation have been tuned to match external measurements, as have the hadronic
cross sections for nucleons and pions. The statistical precision of the flux
predictions is enhanced through reweighting and resampling techniques.
Systematic errors in the flux estimation have been determined by varying
parameters within their uncertainties, accounting for correlations where
