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 ?0 momentum and production angle, for events with a single observed ?0 and no charged pions, are presented and compared to model predictions. These results comprise the first measurement of the ?0 kinematics for this process.

This book was released on 2018 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NONA neutrino experiment based in Fermilab is designed to measure ! e neutrino oscillations. This experiment will give us insight into the properties of massive neutrinos. Neutral current (NC) ;e neutral pion production events can mimic the ! e oscillation signal and therefore are an important background for NONA to understand. Neutral pions decay into two photons which can fake a single electron shower ( e appearance signal) in two ways: either the 2 photons can merge together or one of them may escape detection. In order to constrain this background, NONA utilizes the Near Detector to measure neutral current 0 neutrino interactions. In this analysis, neutrino-Nucleus ( !N) NC 0 interactions with total pion energy greater then 0.3 GeV are studied by selecting two prong events with two final state photons as determined by prong based Convolutional Visual Networks (CVN). The analysis is performed on 3.54x1021 Protons On Target (POT) of NONA Near Detector simulated data and compared to 8.09x1020 POT of data. Optimization of the selection based on fractional cross-section uncertainty and an initial energy resolution study of the final sample are presented. The final 2 prong selection using prong based CVN gave a purity of 74%, selection efficiency of 1.8%, and an expected (NC) ;e neutral pion cross section of 15.2%.

This book was released on 2011 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elucidating the nature of neutrino oscillation continues to be a goal in the vanguard of the efforts of physics experiment. As neutrino oscillation searches seek an increasingly elusive signal, a thorough understanding of the possible backgrounds becomes ever more important. Measurements of neutrino-nucleus interaction cross sections are key to this understanding. Searches for ?? → ?e oscillation - a channel that may yield insight into the vanishingly small mixing parameter ?13, CP violation, and the neutrino mass hierarchy - are particularly susceptible to contamination from neutral current single ?0 (NC 1?0) production. Unfortunately, the available data concerning NC 1?0 production are limited in scope and statistics. Without satisfactory constraints, theoretical models of NC 1?0 production yield substantially differing predictions in the critical E? ̃1 GeV regime. Additional investigation of this interaction can ameliorate the current deficiencies. The Mini Booster Neutrino Experiment (MiniBooNE) is a short-baseline neutrino oscillation search operating at the Fermi National Accelerator Laboratory (Fermilab). While the oscillation search is the principal charge of the MiniBooNE collaboration, the extensive data ( ̃106 neutrino events) offer a rich resource with which to conduct neutrino cross section measurements. This work concerns the measurement of both neutrino and antineutrino NC 1?0 production cross sections at MiniBooNE. The size of the event samples used in the analysis exceeds that of all other similar experiments combined by an order of magnitude. We present the first measurements of the absolute NC 1?0 cross section as well as the first differential cross sections in both neutrino and antineutrino mode. Specifically, we measure single differential cross sections with respect to pion momentum and pion angle. We find the flux-averaged, total cross sections for NC 1?0 production on CH2 to be (4.76 ± 0.05stat ± 0.76sys) x 10-40 cm2/nucleon at Esub?/sub” = 808 MeV for neutrino induced production and (1.48 ± 0.05substat/sub ± 0.23subsys/sub) x 10sup-40/sup cmsup2

This book contains 13 papers that reflect the development of neutrino interactions with the electrons and protons in a fixed-target experiment that, beginning in 1980, grew out of the formal collaboration in high energy physics between Japanese and American institutions. These experiments were crucial to the merger of quantum electrodynamics and quantum weak dynamics, the foundation of electroweak theory today.

This book was released on 2022 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Measurements of neutrino oscillation parameters at accelerator-based experiments require precise knowledge of neutrino interaction cross sections. A significant fraction of neutrino interactions observed in these experiments produce single charged pions. While single charged pion production has been measured on hydrocarbon and water, few precise measurements exist for heavier targets, and there are no high statistics measurements that directly compare pion production on different targets. This thesis measures differential cross sections of muon neutrino charged current single charged pion production with no other mesons in the final state in a neutrino beam with a mean energy of ~ 6 GeV. The pion production is studied on targets of scintillator, carbon, water, iron, and lead at MINERvA, a neutrino cross section experiment located in the NuMI beamline at Fermilab. These measured cross sections are differential in [mu]- and [pi]+ kinematics. A strong suppression of low Q2 and an enhancement of low T[Pi] are observed relative to commonly used neutrino interaction models in both the light and heavy nuclear targets. Incorporation of these observed effects in future neutrino oscillation experiments will improve their ability to measure energy of neutrino interactions, and therefore measure the parameters governing neutrino oscillations."--Page xii

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.
