Description

?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.Typham this is the title: Measurement of the Antineutrino Double-Differential Charged-Current Quasi-Elastic Scattering Cross Section at MINERvA
