Virtual Compton Scattering Cross Section Measurements at Jefferson Lab
ORAL
Abstract
Nucleon polarizabilities are fundamental properties that characterize the response of nucleons to external electromagnetic (EM) fields. In virtual Compton scattering (VCS), the proton's generalized polarizabilities (GPs) provide insight into the spatial distribution of EM-induced deformations in quark densities. The virtuality of the incident photon determines the resolution of the observation, while the momentum of the outgoing real photon sets the scale of the EM perturbation. This talk will highlight recent results from VCS experiments and provide an update on ongoing and upcoming measurements in Hall C at Jefferson Lab.
