Book excerpt: A search for the muon neutrino magnetic moment was conducted using the Mini-BooNE low energy neutrino data. The analysis was performed by analyzing the elastic scattering interactions of muon neutrinos on electrons. The analysis looked for an excess of elastic scattering events above the Standard Model prediction from which a limit on the neutrino magnetic could be set. In this thesis, we report an excess of 15.3 ± 6.6(stat)±4.1(syst) [nu]{sub [mu]e} events above the expected background. At 90% C.L., we derived a limit on the muon neutrino magnetic moment of 12.7 x 10−1° {mu}{sub B}. The other analysis reported in this thesis is a measurement of charged current single pion production (CC[pi]) to charged current quasi elastic (CCQE) interactions cross sections ratio. This measurement was performed with two different fitting algorithms and the results from both fitters are consistent with each other.

Download or read book First Measurement of Muon Neutrino Charged Current Quasielastic (CCQE) Double Differential Cross Section written by and published by . This book was released on 2009 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a high statistics sample of muon neutrino charged current quasielastic (CCQE) events, we report the first measurement of the double differential cross section (d2?/dT{sub {mu}}d cos?{sub {mu}}) for this process. The result features reduced model dependence and supplies the most complete information on neutrino CCQE scattering to date. Measurements of the absolute cross section as a function of neutrino energy (?[E{sub v}{sup QE, RFG}]) and the single differential cross section (d?/dQ{sub QE}2) are also provided, largely to facilitate comparison with prior measurements. This data is of particular use for understanding the axial-vector form factor of the nucleon as well as improving the simulation of low energy neutrino interactions on nuclear targets, which is of particular relevance for experiments searching for neutrino oscillations.

This book was released on 2008 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mini-Booster neutrino experiment (MiniBooNE) at Fermi National Accelerator Laboratory (Fermilab) is designed to search for [nu]{sub [mu]} → [nu]{sub e} appearance neutrino oscillations. Muon neutrino charged-current quasi-elastic (CCQE) interactions ([nu]{sub {mu}} + n → {mu} + p) make up roughly 40% of our data sample, and it is used to constrain the background and cross sections for the oscillation analysis. Using high-statistics MiniBooNE CCQE data, the muon-neutrino CCQE cross section is measured. The nuclear model is tuned precisely using the MiniBooNE data. The measured total cross section is [sigma] = (1.058 ± 0.003 (stat) ± 0.111 (syst)) x 10−38 cm2 at the MiniBooNE muon neutrino beam energy (700-800 MeV). [nu]{sub e} appearance candidate data is also used to search for Lorentz violation. Lorentz symmetry is one of the most fundamental symmetries in modern physics. Neutrino oscillations offer a new method to test it. We found that the MiniBooNE result is not well-described using Lorentz violation, however further investigation is required for a more conclusive result.

Download or read book First Measurement of the Muon Neutrino Charged Current Quasielastic Double Differential Cross Section written by and published by . 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 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: El experimento T2K es un experimento de neutrinos de largo recorrido que utiliza un haz casi puro the neutrinos muónicos. El objetivo principal del experimento es a medida de los parámetros de oscilación del neutrino muónicos. Para conseguir éste objetivo, T2K necesita una rigurosa predicción del índice de interacciones en el detector lejano, Super-KamiokaNDE. El detector cercano de T2K, ND280, calcula el índice de interacciones y estima el número de eventos en el detector lejano. Las interacciones de neutrino muónico de corriente cargada en el detector cercano (ND280) son usadas para predecir el índice de eventos en el detector lejano (Super-KamiokaNDE). Para una mejor restricción de los parámetros de sección eficaz, los cuales dominan el análisis junto con las incertezas de la prediccion del flujo, categorizamos los eventos seleccionados en tres grupos de acuerdo con el número de piones en el estado final. Estas tres categorías permiten un mejor ajuste de la señal del canal de oscilación (Corriente Cargada Quasielástica) y el principal ruído en oscilaciones (Corriente Cargada de 1 Pión Cargado). Actuales y futuros experimentos de neutrinos están limitados por las incertezas en las secciones eficaces de neutrinos. Los modelos actuales de sección eficaz están en tension con los datos experimentales en algunos rangos energéticos. Esto hace que sea critico estudiar secciones eficaces de neutrino--nucleo en todos los canales de interacción posibles. La producción the un solo pión en interacciones de neutrino muónico de corriente cargada es uno de los principales canales en tensión con los modelos. Como segunda contribución, presentamos el cálculo de producción the un solo pión en interacciones de neutrino muónico de corriente cargada usando un enfoque indepenediente del modelo explorando la capacidad total del detector ND280 para establecer las distribuciones cinemáticas del evento. La mejore del conocimiento de las interacciones, y en concreto del canal de producción de un sólo pión, permitirá la reducción de las incertidumbres sistemáticas en el análisis de oscilaciones.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a global endeavor to understand neutrino properties and behavior. It has been experimentally shown that neutrinos oscillate flavor as they transverse space and time as a linear superposition of mass eigenstates. The reconstructed neutrino energy is inherently smeared by the limitation of the detector, fermi motion of the nucleons, and secondary interactions that can occur while the particles are exiting the nucleus therefore neutrino measurements are model dependent. MINERvA was an on-axis short baseline experiment dedicated to measuring neutrino cross-sections. This dissertation encompasses the first in human history of helium and muon neutrino semi-inclusive differential cross section measurement in 1D and 2D muon kinematics.
Book Synopsis Measurement of the Absolute \nu_{\mu}-CCQE Cross Section at the SciBooNE Experiment by :
Download or read book Measurement of the Absolute \nu_{\mu}-CCQE Cross Section at the SciBooNE Experiment written by and published by . This book was released on 2010 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the measurement of the charged current quasi-elastic (CCQE) neutrino-nucleon cross section at neutrino energies around 1 GeV. This measurement has two main physical motivations. On one hand, the neutrino-nucleon interactions at few GeV is a region where existing old data are sparse and with low statistics. The current measurement populates low energy regions with higher statistics and precision than previous experiments. On the other hand, the CCQE interaction is the most useful interaction in neutrino oscillation experiments. The CCQE channel is used to measure the initial and final neutrino fluxes in order to determine the neutrino fraction that disappeared. The neutrino oscillation experiments work at low neutrino energies, so precise measurement of CCQE interactions are essential for flux measurements. The main goal of this thesis is to measure the CCQE absolute neutrino cross section from the SciBooNE data. The SciBar Booster Neutrino Experiment (SciBooNE) is a neutrino and anti-neutrino scattering off experiment. The neutrino energy spectrum works at energies around 1 GeV. SciBooNE was running from June 8th 2007 to August 18th 2008. In that period, the experiment collected a total of 2.65 x 102° protons on target (POT). This thesis has used full data collection in neutrino mode 0.99 x 102° POT. A CCQE selection cut has been performed, achieving around 70% pure CCQE sample. A fit method has been exclusively developed to determine the absolute CCQE cross section, presenting results in a neutrino energy range from 0.2 to 2 GeV. The results are compatible with the NEUT predictions. The SciBooNE measurement has been compared with both Carbon (MiniBoonE) and deuterium (ANL and BNL) target experiments, showing a good agreement in both cases.

Download or read book Measuring Muon-Neutrino Charged-Current Differential Cross Sections with a Liquid Argon Time Projection Chamber written by and published by . This book was released on 2011 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 80 years after its proposed existence, the neutrino remains largely mysterious and elusive. Precision measurements of the neutrino's properties are just now beginning to take place. Such measurements are required in order to determine the mass of the neutrino, how many neutrinos there are, if neutrinos are different than anti-neutrinos, and more. Muon-neutrino charged-current differential cross sections on an argon target in terms of the outgoing muon momentum and angle are presented. The measurements have been taken with the ArgoNeuT Liquid Argon Time Projection Chamber (LArTPC) experiment. ArgoNeuT is the first LArTPC to ever take data in a low energy neutrino beam, having collected thousands of neutrino and anti-neutrino events in the NuMI beamline at Fermilab. The results are relevant for long baseline neutrino oscillation experiments searching for non-zero $\theta_{13}$, CP-violation in the lepton sector, and the sign of the neutrino mass hierarchy, among other things. Furthermore, the differential cross sections are important for understanding the nature of the neutrino-nucleus interaction in general. These measurements represent a significant step forward for LArTPC technology as they are among the first neutrino physics results with such a device.
