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 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 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, I present a measurement of the absolute inclusive cross section of single + production induced by neutral current interactions ( (NCS +)). I also present a method to identify particles stopping in the Fine Grained Detectors (FGDs). An introductory description of neutrino physics, as well as of the T2K experiment and the ND280 tracker system are included for completeness. Other important contributions to the development of the FGDs, including the selection and characterization of the wavelength shifting bers used in these detectors, as well as their commissioning at JPARC, are also discussed in the thesis. The particle identi cation with the FGDs is based on the reconstructed deposited energy versus track length. It is primarily devoted to separate stopping protons from pions. In particular, this method can distinguish between exiting and stopping muons (or pions). In the measurement of (NCS +), the tracker system of the near detector (ND280) of the T2K experiment is used to reconstruct the particles and respective kinematics. It consists of two FGDs and three Time Projection Chambers (TPCs). One of the FGDs provides a target mass of 1 tonne for neutrino interactions, out of it 93% is composed of CH. The number of neutrino interactions used in this thesis corresponds to a total of 1:077 1020 protons on target at the Japan Proton Accelerator Research Complex (JPARC) facility in Tokai, collected during the T2K Run-1 and Run-2 data acquisition periods. Since the ND280 is 2:5 o the neutrino beam direction, its energy spectrum has a narrow width with peak at near 0.6 GeV. The analysis is based on NEUT Monte Carlo (MC) predictions for neutrino-nucleus interactions. The achieved e ciency and purity in the selection of forward-going + are 39% and 21%, respectively, for pions with momentum between 0.2 and 1.1 GeV/c. Systematic errors arising from neutrino ux uncertainties, event reconstruction and neutrino interaction models have been considered in the analysis. The ratio data to MC simulation is data= MC

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

This book was released on 2010 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of the ?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 ?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 ?0 production to the total charge current interaction and the ?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 ?æ → ?e oscillation. The spectrum shape of the ?0 momentum and the distribution of the ?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 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%.

Book excerpt: SciBooNE, located in the Booster Neutrino Beam at Fermilab, collected data from June 2007 to August 2008 to accurately measure muon neutrino and anti-neutrino cross sections on carbon below 1 GeV neutrino energy. SciBooNE is studying charged current interactions. Among them, neutral pion production interactions will be the focus of this poster. The experimental signature of neutrino-induced neutral pion production is constituted by two electromagnetic cascades initiated by the conversion of the [pi]° decay photons, with an additional muon in the final state for CC processes. In this poster, I will present how we reconstruct and select charged-current muon neutrino interactions producing [pi]°'s in SciBooNE.
