The cross sections for neutrino interactions with mineral oil (CH2) are reported for resonantly produced and coherently produced single ?0 events. We measure a resonant single ?0 cross section of ?(v? N ?0) = (0.0129 ± 0.0011(stat.) ± 0.0043(syst.)) x 10-36 cm2/CH2 at a mean neutrino energy of 1.26 GeV. We measure a coherent single ?0 cross section of ?(v? A → v? A ?0) = (0.00077 ± 0.00016 (stat.) ± 0.00036 (syst.)) x 10-36 cm2/CH2 at mean neutrino energy 1.12 GeV.

This book was released on 2010 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The MiniBooNE experiment at the Fermi National Accelerator Laboratory (Fermilab) was designed to search for electron to muon neutrino oscillations at Delta m^2~1 eV^2 using an intense neutrino flux with an average energy of about 700 MeV. From 2002 to 2009 MiniBooNE has accumulated more than 1.0x10^{21} protons on target (POT) in both neutrino and antineutrino modes. MiniBooNE provides a perfect platform for detailed measurements of exclusive and semiinclusive neutrino cross-sections, for which MiniBooNE has the largest samples of events up to date, such as neutral current elastic (NCE), neutral current pi^0, charged current quasi-elastic (CCQE), charged current pi^+, and other channels. These measured cross-sections, in turn, allow to improve the knowledge of nucleon structure. This thesis is devoted to the study of NCE interactions. Neutrino-nucleus neutral current elastic scattering accounts for about 18% of all neutrino interactions in MiniBooNE. Using a high-statistics, high purity sample of NCE interactions in MiniBooNE, the flux-averaged NCE differential cross-section has been measured and is being reported here. Further study of the NCE cross-section allowed for probing the structure of nuclei. The main interest in the NCE cross-section is that it may be sensitive to the strange quark contribution to the nucleon spin, $Delta s$, this however requires a separation of NCE proton from NCE neutron events, which in general is a challenging task. MiniBooNE uses a Cherenkov detector, which imposes restrictions on the measured nucleon kinematic variables, mainly due to the impossibility to reconstruct the nucleon direction below the Cherenkov threshold. However, at kinetic energies above this threshold MiniBooNE is able to identify NCE proton events that do not experience final state interactions. These events were used for the $Delta s$ measurement. In this thesis MiniBooNE reports the NCE (n+p) cross-section, the measurement of the axial mass, $M_A$, and the $Delta s$ parameter from the NCE data.

This book was released on 2014 with total page 147 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: MiniBooNE reports the first absolute cross sections for neutral current single $\pi^0$ production on $CH_2$ induced by neutrino and antineutrino interactions measured from the largest sets of NC $\pi^0$ events collected to date. The principal result consists of differential cross sections measured as functions of $\pi^04$ momentum and $\pi^0$ angle averaged over the neutrino flux at MiniBooNE. We find total cross sections of (4.76+/-0.05_{stat}+/-0.40_{sys})*$10^{-40} cm^2$/nucleon at a mean energy of $E_\nu$= 808 MeV and (1.48+/-0.05_{stat}+/-0.14_{sys})*$10^{-40} cm^2$/nucleon at a mean energy of $E_\nu$= 664 MeV for $\nu_\mu$ and $\bar\nu_\mu$ induced production, respectively. In addition, we have included measurements of the neutrino and antineutrino total cross sections for incoherent exclusive NC $1\pi^0$ production corrected for the effects of final state interactions to compare to prior results.

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 was released on 2010 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high-statistics sample of charged-current muon neutrino scattering events collected with the MiniBooNE experiment is analyzed to extract the first measurement of the double differential cross section (d2?/dT{sub {mu}}d cos?{sub {mu}}) for charged-current quasielastic (CCQE) scattering on carbon. This result features minimal model dependence and provides the most complete information on this process to date. With the assumption of CCQE scattering, the absolute cross section as a function of neutrino energy (?[E{sub {nu}}]) and the single differential cross section (d?/dQ2) are extracted to facilitate comparison with previous measurements. These quantities may be used to characterize an effective axial-vector form factor of the nucleon and to improve the modeling of low-energy neutrino interactions on nuclear targets. The results are relevant for experiments searching for neutrino oscillations.

This book was released on 2015 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos are a nearly massless, neutral particle in the Standard Model that only interact via the weak interaction. Experimental confirmation of neutrino oscillations, in which a neutrino created as a particular type (electron, muon or tau) can be observed as a different type after propagating some distance, earned the 2015 Nobel Prize in Physics. Neutrino oscillation experiments rely on accurate measurements of neutrino interactions with matter, such as that presented here. Neutrinos also provide a unique probe of the nucleus, complementary to electron scattering experiments. This thesis presents a measurement of the charged-current inclusive cross section for muon neutrinos and antineutrinos in the energy range 2 to 50 GeV with the MINERvA detector. MINERvA is a neutrino scattering experiment in the NuMI neutrino beam at Fermilab, near Chicago. A cross section measures the probability of an interaction occurring, measured here as a function of neutrino energy. To extract a cross section from data, the observed rate of interactions is corrected for detector efficiency and divided by the number of scattering nucleons in the target and the flux of neutrinos in the beam. The neutrino flux is determined with the low-$\nu$ method, which relies on the principle that the cross section for interactions with very low recoil energy is nearly constant as a function of neutrino energy. The measured cross section is compared with world data.
