MEASUREMENT OF THE ANTINEUTRINO DOUBLE-DIFFEREN...

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.
