Preliminary Analysis for Pion LT Experiment in Hall C at Jefferson Lab

ORAL

Abstract

 The Pion LT Experiment is a combination of two separately-approved experiments: the measurement of the charged pion form factor to high  Q2 and a scaling study for the L-T separated pion electroproduction cross section. This joint experiment allows for pion form factor extraction to the highest possible Q2, 8.5 GeV2, at Jefferson Lab. The data taken then also coincides with the scaling study at fixed xB = 0.3, 0.4, and 0.55; this will measure the Q2 dependence on the longitudinal and transverse cross sections of pion electroproduction. The latter allows for study of the transition from the non-perturbative to perturbative regions of QCD and possible transverse and regular GPD extraction. The low and mid-epsilon data collection, required for an L-T separation,completed in February 2022 at Hall C of Jefferson Lab. I will review the goals of this experiment and present preliminary analysis of the 2021-2022 data collection from both π+ and π- electroproduction up to Q2 = 8.5 GeV2. The high-epsilon data will be taken in the fall of 2022.
