Book excerpt: SciBooNE is a neutrino scattering experiment located in the Booster Neutrino Beam at Fermilab. It collected data from June 2007 to August 2008 to accurately measure muon neutrino and anti-neutrino cross sections on carbon around 1 GeV neutrino energy. In this thesis we present the results on the measurement of the muon neutrino cross section resulting in a [mu]- plus a single [pi]0 final state (CC- [pi]0 channel). The present work will show the steps taken to achieve this result: from the reconstruction improvements to the background extraction. The flux-averaged CC - [pi]0 production cross section measurement obtained in this thesis [sigma]CC- [pi]0 [Phi] = (5.6 ± 1.9fit ± 0.7beam ± 0.5int - 0.7det) × 10-40 cm2/N at an average energy of 0.89 GeV is found to agree well both with the expectation from the Monte Ca.

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.

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 2011 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we report on a measurement of muon neutrino inclusive charged current interactions on carbon in the few GeV region, using the Fermilab Booster Neutrino Beam. The all neutrino mode data collected in the SciBooNE experiment is used for this analysis. We collected high-statistics CC interaction sample at SciBooNE, and extracted energy dependent inclusive charged current interaction rates and cross sections for a wide energy range from 0.25 GeV to 3̃ GeV. We measure the interaction rates with 6-15% precision, and the cross sections with 10-30% precision. We also made an energy integrated measurements, with the precisions of 3% for the rate, and 8% for the cross section measurements. This is the first measurement of the CC inclusive cross section on carbon around 1 GeV. This inclusive interaction measurement is nearly free from effects of hadron re-interactions in the nucleus. Hence, it is complementary to other exclusive cross section measurements, and essential to understand the neutrino interaction cross sections in the few GeV region, which is relevant to ongoing and future neutrino oscillation experiments. This analysis also provides the normalization for SciBooNE's previous cross section ratio measurements for charged current coherent pion production and neutral current neutral pion production. Then, a precise comparison between our previous measurements and the model predictions becomes possible. The result of the interaction rate measurement is used to constrain the product of the neutrino flux and the cross section at the other experiment on the Fermilab Booster Neutrino Beam: Mini-BooNE. We conducted a search for short-baseline muon neutrino disappearance using data both from SciBooNE and MiniBooNE, to test a possible neutrino oscillation with sterile neutrinos which is suggested by the LSND experiment. With this constraint by SciBooNE, we significantly reduced the flux and the cross section uncertainties at MiniBooNE, and achieved the world best sensitivity for the v? disappearance at 0.5 ?msup2/sup 30 (eV

This book was released on 2010 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 [nu]{sub {mu}} → [nu]{sub e} oscillation - a channel that may yield insight into the vanishingly small mixing parameter [theta]13, CP violation, and the neutrino mass hierarchy - are particularly susceptible to contamination from neutral current single [pi]° (NC 1[pi]°) production. Unfortunately, the available data concerning NC 1[pi]° production are limited in scope and statistics. Without satisfactory constraints, theoretical models of NC 1[pi]° production yield substantially differing predictions in the critical E{sub {nu}} ≈ 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[pi]° 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[pi]° 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[pi]° production on CH2 to be (4.76 ± 0.05{sub stat} ± 0.76{sub sys}) x 10−4° cm2/nucleon at E{sub {nu}} = 808 MeV for neutrino induced production and (1.48 ± 0.05{sub stat} ± 0.23{sub sys}) x 10−4° cm2/nucleon at E{sub {nu}} = 664 MeV for antineutrino induced production.

Download or read book Measurement of Neutrino-Nucleon Neutral-Current Elastic Scattering Cross-section at SciBooNE. written by and published by . This book was released on 2009 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, results of neutrino-nucleon neutral current (NC) elastic scattering analysis are presented. Neutrinos interact with other particles only with weak force. Measurement of cross-section for neutrino-nucleon reactions at various neutrino energy are important for the study of nucleon structure. It also provides data to be used for beam flux monitor in neutrino oscillation experiments. The cross-section for neutrino-nucleon NC elastic scattering contains the axial vector form factor G{sub A}(Q2) as well as electromagnetic form factors unlike electromagnetic interaction. G{sub A} is propotional to strange part of nucleon spin ([Delta]s) in Q2 2!0 limit. Measurement of NC elastic cross-section with smaller Q2 enables us to access [Delta]s. NC elastic cross-sections of neutrino-nucleon and antineutrino-nucleon were measured earlier by E734 experiment at Brookheaven National Laboratory (BNL) in 1987. In this experiment, cross-sections were measured in Q2> 0.4 GeV2 region. Result from this experiment was the only published data for NC elastic scattering cross-section published before our experiment. SciBooNE is an experiment for the measurement of neutrino-nucleon scattering cross-secitons using Booster Neutrino Beam (BNB) at FNAL. BNB has energy peak at 0.7 GeV. In this energy region, NC elastic scattering, charged current elastic scattering, charged current pion production, and neutral current pion production are the major reaction branches. SciBar, electromagnetic calorimeter, and Muon Range Detector are the detectors for SciBooNE. The SciBar consists of finely segmented scintillators and 14336 channels of PMTs. It has a capability to reconstruct particle track longer than 8 cm and separate proton from muons and pions using energy deposit information. Signal of NC elastic scattering is a single proton track. In [nu]p 2![nu]p process, the recoil proton is detected. On the other hand, most of [nu]n 2![nu]n is invisible because there are only neutral particles in final state, but sometimes recoil neutron is scattered by proton and recoil proton is detected. Signal of this event is also single proton track. Event selection for the single proton track events using geometrical and dE/dx information of reconstructed track is performed. After the event selection, NC elastic scattering data sample is obtained. They includes [nu]p 2![nu]p and [nu]n 2![nu]n is obtained. Absolute cross-section as a function of Q2 is evaluated from this NC elastic scattering data sample.

This book was released on 2011 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charged current single pion production (CC?+) and charged current quasi-elastic scattering (CCQE) are the most abundant interaction types for neutrinos at energies around 1 GeV, a region of great interest to oscillation experiments. The cross-sections for these processes, however, are not well understood in this energy range. This dissertation presents a measurement of the ratio of CC?+ to CCQE cross-sections for muon neutrinos on mineral oil (CH2) in the MiniBooNE experiment. The measurement is presented here both with and without corrections for hadronic re-interactions in the target nucleus and is given as a function of neutrino energy in the range 0.4 GeV Esub?/sub 2.4 GeV. With more than 46,000 CC?sup+/sup events collected in MiniBooNE, and with a fractional uncertainty of roughly 11% in the region of highest statistics, this measurement represents a dramatic improvement in statistics and precision over previous CC?
