Inclusive and Exclusive Electron Scattering on ⁴⁰Ar and ⁴⁸Ti to Aid Precision Neutrino Oscillation Experiments

E12-14-012 at Jefferson Lab was conducted to measure the ⁴⁰Ar spectral function, S(k,E), through coincidence electron scattering ⁴⁰Ar(e,e′p). S(k,E) yields the probability of removing a nucleon of momentum k = |k| from the nuclear ground state, leaving the residual nuclear system with excitation energy E. E12-14-012 collected coincidence data from ⁴⁰Ar and ⁴⁸Ti, as well as inclusive data (e,e′) from ¹²C, ⁴⁸Ti and ⁴⁰Ar. Upcoming neutrino oscillation experiments, such as DUNE, will use Liquid Argon Time Projection Chamber (LArTPC) detectors, and hence an understanding of the argon nuclear ground state and its response to neutrino interactions is essential. A direct measurement of the coincidence (e,e′p) cross section on argon will provide the experimental input necessary to constrain the theoretical models used to calculate S(k,E), thus paving the way for a reliable estimate of the neutrino cross sections. After a brief introduction to the motivation and experimental details, the state of the analysis will be presented.
