Physics Nuclear Physics High Resolution Spectrometer R-Function Jefferson Lab Deep Inelastic scattering Experiment E12-06-114 was conducted in Hall A of the Jefferson National Laboratory (JLab) from September 2014 to December 2016. The experiment used exclusive electron-proton scattering to extract the Generalized Parton Distribution Functions (GPDs). The scattered electron was detected in the Hall A Left High Resolution Spectrometer (L-HRS) and the emitted photon in a PbF 2 calorimeter. In general, the recoil proton was not detected, but its mass was reconstructed using the missing mass (M 2 X ) technique, which uses information from the spectrometer and the calorimeter to compute the squared invariant mass of the recoil proton. The purpose of this thesis is to model the High-Resolution Spectrometer (HRS) acceptance at the 1% level. The HRS acceptance is a 4-D region of space, depending on the four correlated target variables (y tg , ¿ tg , f tg , dp tg ). Due to the 4-D structure the acceptance region is difficult to visualize. The R-function, which defines the distance of a particle from the HRS acceptance bound, provides a convenient way to make a single cut and select electrons in the 4-D space. In addition, the Deep Inelastic Scattering (DIS) cross sections was extracted as a benchmark of the overall analysis. The DIS cross section does not change by more than 1% when increasing the cut on the R-value. As a consequence we assign a systematic error of 1% to the HRS acceptance. We can use this information to evaluate, in a preliminary way, the impact of the systematic errors in the Deep Virtual Compton Scattering (DVCS) experiment. 2017 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1512051980809888 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1512051980809888 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
