It introduces the PREX experiment's approach to Coulomb distortion corrections and analyzes dispersion corrections for QWEAK, enhancing the understanding of radiative effects in these measurements.
Findings
Coulomb distortion corrections are significant for PREX.
Dispersion corrections impact the interpretation of QWEAK results.
Improved radiative correction models increase measurement precision.
Abstract
The high precision parity violating electron scattering experiments PREX and QWEAK are sensitive to radiative corrections. In this paper we introduce the PREX experiment that measures the neutron radius of Pb and discuss coulomb distortion corrections. We then discuss dispersion corrections for QWEAK that aims to measure the weak charge of the proton.
