Book excerpt: Production of single .pi./sup 0/ particles in neutrino reactions was studied in an experiment at the Brookhaven National Laboratory Alternating Gradient Synchrotron. The neutral current reactions, .nu.n .-->. .nu.n.pi./sup 0/ and .nu.p .-->. .nu.p.pi./sup 0/, and the charged current reaction, .nu.n .-->. .mu./sup -/p.pi./sup 0/, were investigated. The neutrino detector was made up of optical spark chambers and liquid and solid scintillation counters. The .pi./sup 0/ is detected by observing showers from its decay into two gamma rays. Muons are distinguished from other particles by their long range without interaction. Time of flight measurement is used to discriminate against neutron background. The neutral and charged current events are discussed, and the ratio of neutral current events to charged current events is found to be 0.149 +- 0.048 after corrections. Nuclear charge exchange corrections to this result because the detector contains complex nuclei are also discussed. Kinematic distributions for the final state particles and the p.pi./sup 0/ mass distribution are given. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: Understanding of the [pi]0 production via neutrino-nucleus neutral current interaction in the neutrino energy region of a few GeV is essential for the neutrino oscillation experiments. In this thesis, we present a study of neutral current [pi]0 production from muon neutrinos scattering on a polystyrene (C8H8) target in the SciBooNE experiment. All neutrino beam data corresponding to 0.99 × 1020 protons on target have been analyzed. We have measured the cross section ratio of the neutral current [pi]0 production to the total charge current interaction and the [pi]0 kinematic distribution such as momentum and direction. We obtain [7.7 ± 0.5(stat.) ± 0.5(sys.)] × 10-2 as the ratio of the neutral current neutral pion production to total charged current cross section; the mean energy of neutrinos producing detected neutral pions is 1.1 GeV. The result agrees with the Rein- Sehgal model, which is generally used for the Monte Carlo simulation by many neutrino oscillation experiments. We achieve less than 10 % uncertainty which is required for the next generation search for [nu]æ 2![nu]e oscillation. The spectrum shape of the [pi]0 momentum and the distribution of the [pi]0 emitted angle agree with the prediction, which means that not only the Rein-Sehgal model but also the intra-nuclear interaction models describe our data well. We also measure the ratio of the neutral current coherent pion production to total charged current cross section to be (1.17 ± 0.23) × 10-2 based on the Rein and Sehgal model. The result gives the evidence for non-zero coherent pion production via neutral current interaction at the mean neutrino energy of 1.0 GeV.

This book was released on 2015 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We studied single neutral pion production via muon antineutrino charged-current interactions in plastic scintillator (CH) using the MINERvA detector exposed to the NuMI low-energy, wideband antineutrino beam at Fermilab. Measurement of this process constrains models of neutral pion production in nuclei, which is important because the neutral-current analog is a background for appearance oscillation experiments. Furthermore, the differential cross sections for [pi]0 momentum and production angle, for events with a single observed [pi]0 and no charged pions, are presented and compared to model predictions. These results comprise the first measurement of the [pi]0 kinematics for this process.

Available in PDF, EPUB and Kindle. Book excerpt: Neutral strange particle production in charged-current muon-neutrino interactions have been studied in the Fermilab 15-foot neon bubble chamber. Associated production is expected to be the major source of strange particles in charged-current neutrino interactions. sigma-neutral and xi-minus production by neutrinos was observed. The dependence on various leptonic and hadronic variables is investigated. A fit to single and associated production of s, s/anti-s, and c quarks is described based on the number of single and double strange particle production events. Inclusive neutral strange particle decays (V°) production rates as a fraction of all charged-current events are measured and are tabulated. The lambda/K ratio is found to be 0.39 +- 0.04 and the fraction of lambda coming from sigma-neutral is (16 +- 5)%. The single- and double V° production was used to determine the associated s anti-s production rate and single s-quark production rate. 13 refs., 7 figs., 3 tabs. (LEW).

This book was released on 2009 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding single charged pion production via neutrino-nucleus charged current interaction in the neutrino energy region of a few GeV is essential for future neutrino oscillation experiments since this process is a dominant background for v[mu] → vx oscillation measurements. There are two contributions to this process: single pion production via baryonic resonance (v[mu]N → [mu]- N[pi]+) and coherent pion production interacting with the entire nucleus (v[mu]A → [mu]- A[pi]+), where N is nucleon in the nucleus and A is the nucleus. The purpose of the study presented in this thesis is a precise measurement of charged current single charged pion productions, resonant and coherent pion productions, with a good final state separation in the neutrino energy region of a few GeV. In this thesis, we focus on the study of charged current coherent pion production from muon neutrinos scattering on carbon, v[mu] 12C → [mu]-12C[pi]+, in the SciBooNE experiment. This is motivated by the fact that without measuring this component first, the precise determination of resonant pion production cross section can not be achieved since the contribution of coherent pion production in the region of small muon scattering angle is not small. Furthermore, the coherent process is particularly interesting because it is deeply rooted in fundamental physics via Adler's partially conserved axial-vector current theorem. We took data from June 2007 until August 2008, in both the neutrino and antineutrino beam. In total, 2.52 x 1020 protons on target were collected. We have performed a search for charged current coherent pion production by using SciBooNE's full neutrino data set, corresponding to 0.99 x 1020 protons on target. No evidence for coherent pion production is observed. We set 90% confidence level upper limits on the cross section ratio of charged current coherent pion production to the total charged current cross section at 0.67 x 10-2 at mean neutrino energy 1.1 GeV and 1.36 x 10-2 at mean neutrino energy 2.2 GeV. We reveal that the Rein-Sehgal model widely used in neutrino oscillation experiments breaks down at the neutrino energy region of a few GeV. This creates active controversies on the model of coherent pion production, and the understanding of coherent pion production is being progressed. In addition, future prospects of measurements of charged current single charged pion production in SciBooNE are discussed.

This book was released on 2005 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The MiniBooNE neutrino beam and detector at Fermilab are used to study the production of neutral current {pi}{sup 0} events. The cross sections for neutrino interactions with mineral oil (CH{sub 2}) are reported for resonantly produced and coherently produced single {pi}{sup 0} events. We measure a resonant single {pi}{sup 0} cross section of {sigma}({nu}{sub {mu}} N {pi}{sup 0}) = (0.0129 {+-} 0.0011(stat.) {+-} 0.0043(syst.)) x 10{sup -36} cm{sup 2}/CH{sub 2} at a mean neutrino energy of 1.26 GeV. We measure a coherent single {pi}{sup 0} cross section of {sigma}({nu}{sub {mu}} A {yields} {nu}{sub {mu}} A {pi}{sup 0}) = (0.00077 {+-} 0.00016 (stat.) {+-} 0.00036 (syst.)) x 10{sup -36} cm{sup 2}/CH{sub 2} at mean neutrino energy 1.12 GeV.

This book was released on 2018-07-21 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the upgrade of the Super-Kamiokande (SK) detector, which consists in the addition of a salt of gadolinium into the detector’s water, the goal being to endow it with a very high-efficiency ability to detect neutrons: the SuperK-Gd project. This will substantially improve the scientific value of the SK detector because, among others, neutron production is related to the matter–antimatter character of the interacting neutrino. In this book the authors develop several procedures for maximizing the impact of neutron tagging in various physics analyses involving a broad range of neutrino energy. They thoroughly study the impact of new backgrounds introduced by Gd in key physics analyses, most remarkably including the search for the Diffuse Supernova Neutrino Background. At GeV energies, the neutron tagging improvements are evaluated by performing a complete neutrino oscillation sensitivity study using atmospheric and long baseline neutrinos, with a focus on the neutrino mass hierarchy and the leptonic CP violation. In order to prove the relevance of neutron tagging with the available data, the authors apply the neutron-tagging tools developed here to the 4th phase of the SK detector, which is already capable of detecting a low fraction of the neutrons produced through hydrogen-neutron captures. A global oscillation analysis of the SK’s atmospheric neutrino data is also conducted.
