Abstract

The Q-weak experiment at Jefferson Laboratory measured the parity violating asymmetry (A_PV) in elastic electron-proton scattering at small momentum transfer squared (Q²=0.025 (GeV/c)²), with the aim of extracting the proton’s weak charge (QWp) to an accuracy of 5 %. As one of the major uncertainty contribution sources to QWp, Q² needs to be determined to ∼1 % so as to reach the proposed experimental precision. For this purpose, two sets of high resolution tracking chambers were employed in the experiment, to measure tracks before and after the magnetic spectrometer. Data collected by the tracking system were then reconstructed with dedicated software into individual electron trajectories for experimental kinematics determination. The Q-weak kinematics and the analysis scheme for tracking data are briefly described here. The sources that contribute to the uncertainty of Q² are discussed, and the current analysis status is reported.
