Title: Measurement of the (e,e') cross section for12C, 48Ti, 27Al and 40Ar

Abstract

Many experiments have found that neutrinos have three different flavors, and they can transform from each other. Each flavor is a mixture of three nonzero mass states. In neutrino oscillation experiments, the uncertainty of the extracted oscillation parameters is dependent on the neutrino-nucleus cross section. In recent years various experiments provided precise neutrino and anti-neutrino cross section measurements and they have shown the inability of current Monte Carlo simulations to reproduce the data. A more accurate nuclear structure model of the target employed in neutrino detector is urgently needed to improve the precision of long baseline neutrino experiments. Electron scattering has been one of the most powerful methods of obtaining information about cross sections in the past. In the upcoming deep underground neutrino experiment (DUNE), Liquid Argon Time Projection Chambers (LArTPCs) will be used as the detector technology and argon will be used as the nuclear target. There are very few data available on argon and there is not an accurate nuclear model that describes them accurately, at ~5% level. We have performed an electron-argon scattering experiment at Jefferson Lab (E12-14-012) to provide accurate data that will help build a reliable nuclear model for describing neutrino-argon scattering. The JLab E12-14-012more » experiment has successfully taken data in Hall A at the Thomas Jefferson National Accelerator Facility between February and March of 2017. We collected data for the inclusive (e,e') and exclusive (e,e'p) processes for a variety of targets (argon, titanium, aluminum, carbon) at a wide range of kinematic settings. This thesis will present the results of the inclusive double differential cross sections for carbon, titanium, aluminum and argon at beam energy E = 2:222 GeV and scattering angle theta = 15:541 deg with total uncertainties smaller than 5%. The kinematic settings covered a broad range of energy transfers, including deep inelastic scattering (DIS), delta production, and quasielastic scattering.« less
