$\mathrm F_{2}^{P}$ and $\mathrm F_{2}^{d}$ extractions at large Bjorken X from $\mathrm h(e,e^{\prime})$ and $\mathrm d(e,e^{\prime})$ cross sections measured during E12-10-002 in Hall C at Jefferson Lab

Abstract

Extractions of the $\mathrm F_{2}$ structure functions from inclusive $\mathrm h(e,e^{\prime})$ and $\mathrm d(e,e^{\prime})$ reactions are important for the study of nucleon structure. Such extractions help with constraining the PDF (specially at large Bjorken X), facilitate the studies of Quark Hadron Duality and are important for non-singlet moments calculation as a test of LQCD.\par Experiment E12-10-002 ran in Hall C at JLab in spring 2018 with a focus on measuring the precession cross sections on h and d for $\mathrm F_{2}$ structure functions extraction. Our measurements cover a large kinematic range in X from 0.2 to 1.0, and in $\mathrm Q^{2}$ from 4 to 16 $\mathrm GeV^{2}$.\par I will show the preliminary results of $\mathrm h(e,e^{\prime})$, $\mathrm d(e,e^{\prime})$ cross sections, d/h cross section ratios and $\mathrm F_{2}$ structure functions. I will also discuss the comparison between our data and models such as Christy$'$s f1f220 , CTEQ-JLAB (CJ) and Kulagin (DIS and hybrid) .
