Available in PDF, EPUB and Kindle. Book excerpt: Here, the MINERvA Collaboration reports a novel study of neutrino-nucleus charged-current deep inelastic scattering (DIS) using the same neutrino beam incident on targets of polystyrene, graphite, iron, and lead. Results are presented as ratios of C, Fe, and Pb to CH. The ratios of total DIS cross sections as a function of neutrino energy and flux-integrated differential cross sections as a function of the Bjorken scaling variable x are presented in the neutrino-energy range of 5-50 GeV. Based on the predictions of charged-lepton scattering ratios, good agreement is found between the data and prediction at medium x and low neutrino energy. However, the ratios appear to be below predictions in the vicinity of the nuclear shadowing region, x

This book was released on 2016-11-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis details significant improvements in the understanding of the nuclear EMC effect and nuclear shadowing in neutrino physics, and makes substantial comparisons with electron scattering physics. Specifically, it includes the first systematic study of the EMC ratios of carbon, iron and lead to plastic scintillator of neutrinos. The analysis presented provides the best evidence to date that the EMC effect is similar between electrons and neutrinos within the sensitivity of the data. Nuclear shadowing is measured systematically for the first time with neutrinos. In contrast with the data on the EMC effect, the data on nuclear shadowing support the conclusion that nuclear shadowing may be stronger for neutrinos than it is for electrons. This conclusion points to interesting new nuclear physics.
Book Synopsis Probing Particle Physics With Neutrino Telescopes by : Carlos Perez De Los Heros
Download or read book Probing Particle Physics With Neutrino Telescopes written by Carlos Perez De Los Heros and published by World Scientific. This book was released on 2019-12-23 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the reader to how fundamental topics in particle physics can be studied with the largest neutrino telescopes currently in operation. Due to their large size, reaching cubic-kilometer volumes, and their wide energy response, these unusual detectors can provide insight on neutrino oscillations, dark matter searches or searches for exotic particles, new neutrino interactions or extra dimensions, among many other topics.Lacking a man-made neutrino 'beam', neutrino telescopes use the copious flux of neutrinos continuously produced by cosmic rays interacting in the Earth's atmosphere, as well as neutrinos from astrophysical origin. They have therefore access to neutrinos of higher energies and much longer baselines than those produced in present accelerators, being able to search for new physics at complementary scales than currently available in particle physics laboratories around the world.Written by carefully chosen experts in the field, the book introduces each topic in a pedagogical way apt not only to professionals, but also to students or the interested reader with a background in physics.
Book Synopsis Measurement of the Antineutrino Double-Differential Charged-Current Quasi-Elastic Scattering Cross Section at MINERvA by : Cheryl E. Patrick
Download or read book Measurement of the Antineutrino Double-Differential Charged-Current Quasi-Elastic Scattering Cross Section at MINERvA written by Cheryl E. Patrick and published by Springer. 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.

Download or read book MINERvA Measurement of Neutrino Charged-Current Cross Section Ratios of Nuclei C, Fe, and Pb to CH at Energies of a Few GeV. written by and published by . 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.

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.
Book Synopsis The Impact of New Neutrino DIS and Drell-Yan Data on Large-x Parton Distributions by :
Download or read book The Impact of New Neutrino DIS and Drell-Yan Data on Large-x Parton Distributions written by and published by . This book was released on 2007 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: New data sets have recently become available for neutrino and antineutrino deep inelastic scattering on nuclear targets and for inclusive dimuon production in pp and pd interactions. These data sets are sensitive to different combinations of parton distribution functions in the large-x region and, therefore, provide different constraints when incorporated into global parton distribution function fits. We compare and contrast the effects of these new data on parton distribution fits, with special emphasis on the effects at large x. The effects of the use of nuclear targets in the neutrino and antineutrino data sets are also investigated.

This book was released on 2021 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: "MINERvA, or Main INjector ExpeRiment for v-A, at Fermilab, is an experiment dedicated to the study of neutrino-nucleus interactions in the GeV regime. Its goal is to illustrate the interplay between hadronic and nuclear physics and measure intranuclear dynamics crucial for the present and future neutrino oscillation measurements. We first measure a set of variables sensitive to how Monte Carlo (MC) simulations of neutrino-nucleus interactions implement binding energy and then move on to measure the antineutrino CCQE cross section on the hydrogen targets in MINERvA's CH detector. We have developed a method to preferentially select events on the hydrogen by comparing outgoing neutrons' directions to theoretical neutron directions assuming two-body interactions. We measured the cross section, extracted the axial form factor, and performed a Z-expansion fit. We observe larger values in the axial form factor at high Q2 than current best fits. Finally, we show a preliminary selection of events with both protons and neutrons to investigate nuclear processes responsible for producing these final states"--Page xi.

Available in PDF, EPUB and Kindle. Book excerpt: "The phenomenon of neutrino oscillation is becoming increasingly understood with results from accelerator-based and reactor-based experiments, but unanswered questions remain. The proper ordering of the neutrino mass eigenstates that compose the neutrino flavor eigenstates is not completely known. We have yet to detect CP violation in neutrino mixing, which if present could help explain the asymmetry between matter and anti-matter in the universe. We also have not resolved whether sterile neutrinos, which do not interact in any Standard Model interaction, exist. Accelerator-based experiments appear to be the most promising candidates for resolving these questions; however, the ability of present and future experiments to provide answers is likely to be limited by systematic errors. A significant source of this systematic error comes from limitations in our knowledge of neutrino-nucleus interactions. Errors on cross-sections for such interactions are large, existing data is sometimes contradictory, and knowledge of nuclear effects is incomplete. One type of neutrino interaction of particular interest is charged current quasi-elastic (CCQE) scattering, which yields a final state consisting of a charged lepton and nucleon. This process, which is the dominant interaction near energies of 1 GeV, is of great utility to neutrino oscillation experiments since the incoming neutrino energy and the square of the momentum transferred to the final state nucleon, Q2, can be reconstructed using the final state lepton kinematics. To address the uncertainty in our knowledge of neutrino interactions, many experiments have begun making dedicated measurements. In particular, the MINERvA experiment is studying neutrino-nucleus interactions in the few GeV region. MINERvA is a fine-grained, high precision, high statistics neutrino scattering experiment that will greatly improve our understanding of neutrino cross-sections and nuclear effects that affect the final state particles in neutrino interactions. We present the first cross-section measurement for MINERvA, the differential cross-section d[sigma]/dQ2 for muon anti-neutrino CCQE scattering on polystyrene scintillator (CH) as well as comparisons to several final state models"--Page v-vi.

Available in PDF, EPUB and Kindle. Book excerpt: Kinematic imbalance of the final-state particles in the plane transverse to the neutrino direction provides a sensitive probe of nuclear effects. In this contribution, we report the MINERvA measurement of the single-transverse kinematic imbalance in neutrino charged-current quasielastic-like events on CH targets. To improve the momentum measurements of the final-state particles, we develop a method to select elastically scattering contained (ESC) protons and a general procedure to correct the transverse momentum scales.

This book was released on 2008-01-15 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: NuInt07, the fifth in a series of international workshops, was held at Fermi National Accelerator Laboratory in Batavia, IL. It was the successful continuation of a series of workshops focused solely on the understanding and measurement of low energy neutrino-nucleus interactions. Neutrino cross sections in the few-GeV energy range are an important ingredient for neutrino oscillation experiments as well as being interesting in their own right. Such measurements and their accompanying theoretical calculations had not been updated for decades. The goal of this workshop series has been to remedy this situation by providing an environment where both experimentalists and theorists in nuclear and high energy physics can come together to review and discuss recent progress in neutrino-nucleus measurements and calculations.

Available in PDF, EPUB and Kindle. Book excerpt: Neutrino experiments use heavy nuclei (C, Fe, Pb) to achieve necessary statistics. However, the use of heavy nuclei exposes these experiments to the nuclear dependence of neutrino-nucleus cross sections, which are poorly known and difficult to model. This dissertation presents an analysis of the nuclear dependence of inclusive chargedcurrent neutrino scattering using events in carbon, iron, lead, and scintillator targets of the MINERvA detector. MINERvA (Main INjector ExpeRiment for -A) is a few-GeV neutrinonucleus scattering experiment at Fermilab.

Book excerpt: The MINERvA experiment is a dedicated cross-section experiment whose aim is to measure neutrino cross sections for inclusive and exclusive final states on several nuclei. The detector is fully commissioned and began running in March 2010. As a dedicated cross-section experiment, MINERvA has a particular need to know the incident neutrino flux: both the absolute level and the energy dependence. In these proceedings we describe the MINERvA detector, give an update on the experimental status, and discuss the means to determine the neutrino flux. The MINERvA experiment is now running and has completed 25% of its full Low Energy run. There are various techniques planned for understanding the flux, including taking neutrino data at several different beam configurations. The experiment has gotten a first glimpse of two of the six configurations, and completed four horn current scans. Because of its exclusive final state reconstruction capabilities MINERvA can provide the much needed input for current and future oscillation experiments. The inclusive final state measurements and comparisons of nuclear effects across as many states as possible will provide new insights into neutrino-nucleus scattering.
