Book excerpt: This thesis presents the measurement of energy dependence of the neutrino-nucleon inclusive charged current cross section on an isoscalar target in the range 3-50 GeV for neutrinos and 5-50 GeV energy range for antineutrinos. The data set was collected with the MINOS Near Detector using the wide band NuMI beam at Fermilab. The size of the charged current sample is 1.94 x 106 neutrino events and 1.60 x 105 antineutrino events. The flux has been extracted using a low hadronic energy sub-sample of the charged current events. The energy dependence of the cross section is obtained by dividing the charged current sample with the extracted flux. The neutrino and antineutrino cross section exhibits a linear dependence on energy at high energy but shows deviations from linear behavior at low energy. We also present a measurement of the ratio of antineutrino to neutrino inclusive cross section.

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.

Download or read book Measurement of the Muon Neutrino Inclusive Charged Current Cross Section on Iron Using the MINOS Detector written by and published by . This book was released on 2010 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neutrinos at the Main Injector (NuMI) facility at Fermi National Accelerator Laboratory (FNAL) produces an intense muon neutrino beam used by the Main Injector Neutrino Oscillation Search (MINOS), a neutrino oscillation experiment, and the Main INjector ExpeRiment v-A, (MINERv A), a neutrino interaction experiment. Absolute neutrino cross sections are determined via [sigma]v = N v/[Phi]v, where the numerator is the measured number of neutrino interactions in the MINOS Detector and the denominator is the flux of incident neutrinos. Many past neutrino experiments have measured relative cross sections due to a lack of precise measurements of the incident neutrino flux, normalizing to better established reaction processes, such as quasielastic neutrino-nucleon scattering. But recent measurements of neutrino interactions on nuclear targets have brought to light questions about our understanding of nuclear effects in neutrino interactions. In this thesis the v[mu] inclusive charged current cross section on iron is measured using the MINOS Detector. The MINOS detector consists of alternating planes of steel and scintillator. The MINOS detector is optimized to measure muons produced in charged current v[mu] interactions. Along with muons, these interactions produce hadronic showers. The neutrino energy is measured from the total energy the particles deposit in the detector. The incident neutrino flux is measured using the muons produced alongside the neutrinos in meson decay. Three ionization chamber monitors located in the downstream portion of the NuMI beamline are used to measure the muon flux and thereby infer the neutrino flux by relation to the underlying pion and kaon meson flux. This thesis describes the muon flux instrumentation in the NuMI beam, its operation over the two year duration of this measurement, and the techniques used to derive the neutrino flux.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The total cross sections are important ingredients for the current and future neutrino oscillation experiments. We present measurements of the total charged-current neutrino and antineutrino cross sections on scintillator (CH) in the NuMI low-energy beamline using an in situ prediction of the shape of the flux as a function of neutrino energy from 2-50 GeV. This flux prediction takes advantage of the fact that neutrino and antineutrino interactions with low nuclear recoil energy ([nu]) have a nearly constant cross section as a function of incident neutrino energy. This measurement is the lowest energy application of the low-[nu] flux technique, the first time it has been used in the NuMI antineutrino beam configuration, and demonstrates that the technique is applicable to future neutrino beams operating at multi-GeV energies. Lastly, the cross section measurements presented are the most precise measurements to date below 5 GeV.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a measurement of charged-current inclusive cross sections of muon neutrino and antineutrino interaction on carbon, and antineutrino to neutrino cross section ratio, r, in the energy range 2 - 22 GeV, with data collected in the MINERA experiment. The dataset corresponds to an exposure of 3.21020 protons on target (POT) for neutrinos and 1.01020 POT for antineutrinos. Measurement of neutrino and antineutrino charged-current inclusive cross sections provides essential constraints for future long baseline neutrino oscillation experiment at a few GeV energy range. Our measured antineutrino cross section has an uncertainty in the range 6.1% - 10.5% and is the most precise measurement below 6 GeV to date. The measured r has an uncertainty of 5.0% - 7.5%. This is the rst measurement below 6 GeV since Gargamelle in 1970s. The cross sections are measured as a function of neutrino energy by dividing the eciency corrected charged-current sample with extracted uxes. Fluxes are obtained using the low- method, which uses low hadronic energy subsamples of charged-current inclusive sample to extract ux. Measured cross sections show good agreement with the prediction of neutrino interaction models above 7 GeV, and are about 10% below the model below 7 GeV. The measured r agrees with the GENIE model [1] over the whole energy region. The measured cross sections and r are compared with world data.

This book was released on 2017-11-15 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis represents the first double differential measurement of quasi-elastic anti-neutrino scattering in the few GeV range--a region of substantial theoretical and experimental interest as it is the kinematic region where studies of charge-parity (CP) violation in the neutrino sector most require precise understanding of the differences between anti-neutrino and neutrino scatter. This dissertation also presents total antineutrino-scintillator quasi-elastic cross sections as a function of energy, which is then compared to measurements from previous experiments. Next-generation neutrino oscillation experiments, such as DUNE and Hyper-Kamiokande, hope to measure CP violation in the lepton sector. In order to do this, they must dramatically reduce their current levels of uncertainty, particularly those due to neutrino-nucleus interaction models. As CP violation is a measure of the difference between the oscillation properties of neutrinos and antineutrinos, data about how the less-studied antineutrinos interact is especially valuable. The measurement described herewith determines the nuclear and instrumental effects that must be understood to undertake precision neutrino physics. As well as being useful to help reduce oscillation experiments' uncertainty, this data can also be used to study the prevalence of various correlation and final-state interaction effects within the nucleus. In addition to being a substantial scientific advance, this thesis also serves as an outstanding introduction to the field of experimental neutrino physics for future students.

This book was released on 2008 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Main Injector Neutrino Oscillation Search (MINOS) is a long baseline neutrino oscillation experiment based at the Fermi National Accelerator Laboratory (FNAL) in Chicago, Illinois. MINOS measures neutrino interactions in two large iron-scintillator tracking/sampling calorimeters; the Near Detector on-site at FNAL and the Far Detector located in the Soudan mine in northern Minnesota. The Near Detector has recorded a large number of neutrino interactions and this high statistics dataset can be used to make precision measurements of neutrino interaction cross sections. The cross section for charged-current quasi-elastic scattering has been measured by a number of previous experiments and these measurements disagree by up to 30%. A method to select a quasi-elastic enriched sample of neutrino interactions in the MINOS Near Detector is presented and a procedure to fit the kinematic distributions of this sample and extract the quasi-elastic cross section is introduced. The accuracy and robustness of the fitting procedure is studied using mock data and finally results from fits to the MINOS Near Detector data are presented.

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 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intrinsic electron anti-neutrino component in the muon anti-neutrino Tokai to Kamiokande (T2K) beam represents the largest irreducible background for the muon anti-neutrino to the electron anti-neutrino appearance measurement at Super-Kamiokande. In this thesis, the electron anti-neutrino charged-current inclusive cross-section on carbon is measured using the T2K near detector (ND280). The measurement is performed in two steps: the selection of the electron anti-neutrino events, and the correction of the detector inefficiency and mis-reconstruction (unfolding). In the selection step, a new particle identification based on the Boosted Decision Tree (BDT) was developed. The Particle IDentifications (PIDs) from the Fine-Grained Detectors (FGDs), Time Projection Chambers (TPCs) and Electromagnetic Calorimeters (ECALs) are used as input for the BDT to select the positron track; a characteristic feature of the charged-current interaction of the electron anti-neutrino. The BDT parameters were tuned to maximize the selection efficiency, purity and Kolmogorov-Smirnov (KS) test. The uncertainty on the BDT output test statistic was calculated by propagating the input variables systematics using Monte Carlo (MC) simulation. Moreover, we have developed an improved unfolding algorithm based on the D'Agostini 2010 method as well as a framework to test the unfolding performance. In order to to constrain the gamma background, we have also constructed a control sample to select the gamma events and to use it in the simultaneous unfolding framework. Finally, we measured the electron anti-neutrino charged-current inclusive cross-section on carbon with and without using the control sample.

This book was released on 2013 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents the first measurement of the muon antineutrino charged current quasi-elastic double-differential cross section. These data significantly extend the knowledge of neutrino and antineutrino interactions in the GeV range, a region that has recently come under scrutiny due to a number of conflicting experimental results. To maximize the precision of this measurement, three novel techniques were employed to measure the neutrino background component of the data set. Representing the first measurements of the neutrino contribution to an accelerator-based antineutrino beam in the absence of a magnetic field, the successful execution of these techniques carry implications for current and future neutrino experiments.
