Virtual Compton scattering on the proton below pion threshold
Abstract
The technique of Virtual Compton Scattering (VCS) has become a valuable tool in the study of nucleon structure. In this thesis we describe the use of VCS to measure generalized Polarizabilities (GPs) of the proton. The GPs are fundamental properties of the proton and their precise measurement will set limits on models of nucleon structure. The VCS experiment was performed at the MIT-Bates Linear Accelerator Center at fixed virtual photon three-momentum of qi = 240 MeV/c and virtual photon polarization ϵ = 0.9, corresponding to a four-momentum transfer squared of Q 2 ∼ 0.06 GeV2/c2. At this low momentum transfer the measured coincident cross sections are proportional to response functions PLL-PTT/ϵ and PLT. The response functions are linear combinations of the GPs.
