This book was released on 2017 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sample of charged-current single pion production events for the semi- exclusive channel [nu]æ + CH 2!æ-[pi]0 + nucleon(s) has been obtained using neutrino exposures of the MINERvA detector. Differential cross sections for muon momentum, muon production angle, pion momentum, pion production angle, and four-momentum transfer square Q2 are reported and are compared to a GENIE-based simulation. The cross section versus neutrino energy is also re- ported. The effects of pion final-state interactions on these cross sections are investigated. The effect of baryon resonance suppression at low Q2 is examined and an event re-weight used by two previous experiments is shown to improve the data versus simulation agreement. The differential cross sections for Q2 for E[nu]

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
Book Synopsis An Improved Measurement of the Muon Neutrino Charged Current Quasi-elastic Cross-section on Hydrocarbon at Minerva by : Dun Zhang
Download or read book An Improved Measurement of the Muon Neutrino Charged Current Quasi-elastic Cross-section on Hydrocarbon at Minerva written by Dun Zhang and published by . This book was released on 2017 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrino interactions in the detectors of long baseline oscillation experiments are analyzed to determine the neutrino flavor and energy spectrum, allowing the neutrino mass ordering and mixing parameters to be determined. For neutrino interactions below the pion production threshold, the dominant reaction is charged current quasi-elastic (CCQE) scattering. Oscillation experiments are made of heavy nuclei so the QE process occurs on nucleons that are embedded in the nuclear environment. Predictions of the QE cross-section suffer from significant uncertainties due to our understanding of that nuclear environment and the way it is probed by the weak interaction. I have developed a new technique to reduce the inelastic background to CCQE process by identifying the "Michel electrons" produced by pions. Additionally an updated neutrino flux was used to extract the cross-section and estimates for some sources of systematic uncertainties have been improved. The measured cross-section is compared to several theoretical models and the effect that the signal definition ("CCQE" vs "CCQE-like") has on the measurement is also explored.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The MINERvA Experiment (Main Injector Experiment v A interaction) [1] is a highly segmented detector of neutrinos, able to record events with high precision (over than thirteen million event in a four year run), using the NuMI Beam (Neutrino Main Injector) at the Fermi National Accelerator Laboratory [2]. This thesis presents a measurement of the Charged Current Quasi-Elastic Like1 v[mu] interaction on polystyrene scintillator (CH) in the MINERvA experiment with neutrino energies between 1.5 and 10 GeV. We use data taken between2 March 2010 and April 2012. The interactions were selected by requiring a negative muon, a reconstructed and identified proton, no michel electrons in the final state (in order to get rid of soft pions decaying) and a low calorimetric recoil energy away from the interaction vertex. The analysis is performed on 66,214 quasi-elastic like event candidates in the detectors tracker region with an estimated purity of 74%. The final measurement reported is a double differential cross sections in terms of the muon longitudinal and transversal momentum observables.

This book was released on 2012 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The MINERvA detector collected 1.2 x 1020 POT of muon neutrino data with the NuMI beam at Fermi National Laboratory from 03/2010 to 07/2010. I will describe an analysis to identify two track charged current muon neutrino quasi-elastic interactions using this data set. The final state muon was identified by curvature using the MINOS detector. The final state contained proton was identified by the energy deposited per unit length at the end of the track. Two additional cuts were applied to separate signal from background: a cut on the extra energy in the event and a cut on a proton energy dependent variable. The differential cross section using this selection is presented. An initial list of systematic errors is introduced and calculated. In addition to this analysis work, I also developed both pattern recognition schemes used by the experiment, wrote MINOS muon track matching algorithms, implemented a Kalman Filter track fitting algorithm and contributed to various other tasks to the MINERvA experiment; I will provide an explanation of these. I will also give a brief overview of neutrino physics, the NuMI beam, and the MINERvA detector.

Book Synopsis Measurement of the Muon Neutrino Charged Current Interactions and the Muon Neutrino Single Pion Cross Section on CH Using the T2K Near Detector by : Raquel Castillo Fernández

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.

Download or read book Measurement of Neutrino and Antineutrino Charged-Current Inclusive Cross Sections with the MINERvA Detector written by and published by . 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.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "MINERvA is a neutrino-nucleus scattering experiment that investigates the effects of the nuclear medium on neutrino interactions on different targets in the energy range of the few-GeV. One of the motivations of those measurements is to provide a solid understanding of cross-sections in that energy regime that can be useful for the physics program of the current and future neutrino oscillation experiments. Because of the different interaction types in the few-GeV regime, MINERvA specializes in studying interactions with several final state production channels. Previous measurements of single-[pi]0 production on hydrocarbon using a neutrino beam with a mean energy of 3 GeV have shown remarkable discrepancies between the predicted and the observed cross-sections in the low-Q2 regime. Such results were consistent with similar measurements from the MiniBooNE and MINOS experiments, both made of carbon-based detectors. This thesis will describe the results of the novel analysis of neutrino-induced single-[pi]0 production on lead and iron using a neutrino beam with a mean energy of 6 GeV. This thesis work aims to investigate similar suppression effects at low momentum transfer and offer a glance at those effects in a heavy nuclei medium"--Page xvi.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The MINERvA experiment is designed to measure neutrino cross sections for different nuclei using substantially similar fiducial and tracking environments. This allows for reduced systematics in the ratio to better see the evolution of the cross section with the size of the nucleus. The first such result is an inclusive charged current cross section ratio as a function of energy from and the kinematic quantity Bjorken x for nuclei Pb, Fe, and C relative to plastic scintillator CH. The measurement is made for neutrino energies from 2 to 20 GeV. In the past, charged lepton scattering ratios of heavier nuclei to deuterium have revealed interesting structure such as the EMC effect. These ratios were restricted to purely deep inelastic scattering data whereas these ratios to different nuclei in MINERvA are sensitive to the elastic scattering as well as resonance production regions. Significant deviations from the baseline scattering model are observed, and suggest new theory work to investigate these ratios.

Download or read book Electron Neutrino Charged-Current Quasielastic Scattering in the MINERvA Experiment written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The electron-neutrino charged-current quasielastic (CCQE) cross section on nuclei is an important input parameter to appearance-type neutrino oscillation experiments. Current experiments typically work from the muon neutrino cross section and apply corrections from theoretical arguments to obtain a prediction for the electron neutrino cross section, but to date there has been no experimental verification of the estimates for this channel at an energy scale appropriate to such experiments. We present the first measurement of an exclusive reaction in few-GeV electron neutrino interactions, namely, the cross section for a CCQE-like process, made using the MINERvA detector. The result is given as differential cross-sections vs. the electron energy, electron angle, and square of the four-momentum transferred to the nucleus, $Q^2$. We also compute the ratio to a muon neutrino cross-section in $Q^2$ from MINERvA. We find satisfactory agreement between this measurement and the predictions of the GENIE generator.

Download or read book Measurement of Charged Kaon Production by Neutrinos at MINERvA. written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Charged kaon production by atmospheric neutrinos is a background in searches for the proton decay $p \rightarrow K^{+} \bar{\nu}$. This channel is well motivated theoretically, and is favored by Supersymmetric Grand Unified Theories. Measurements of neutrino-induced $K^{+}$ production are important inputs for current and future proton decay searches at Super-K, Hyper-K and DUNE. The MINERvA neutrino-nucleus cross section experiment at Fermilab uses timing information to reconstruct $K^{+}$ decay-at-rest events. Differential cross section measurements are presented for both charged- and neutral-current neutrino interactions on plastic scintillator (CH). The cross section in $K^{+}$ kinetic energy, $d\sigma/dT_K$, is observed to be relatively flat between 0 and 500 MeV for both charged- and neutral-current scattering. Its shape is in good agreement with the prediction by the GENIE neutrino event generator when final-state interactions are included. A measurement of the hadronic visible energy in neutral-current $K^{+}$ events is also presented, as proton decay backgrounds come from events with very low visible energy. The spectrum is observed to be slightly softer in data than in \genie. A search for charged-current coherent $K^{+}$ production, $\nu_{\mu}A\rightarrow\mu^{-}K^{+}A$, is also presented. This rare process brings a $K^{+}$ on shell and leaves the target nucleus in its ground state. We find the first experimental evidence for the process at $3\sigma$ significance.
