Abstract

Virtual Compton scattering (VCS) on the proton has been studied at the Jefferson Laboratory using the exclusive photon electroproduction reaction ep → epγ. This paper gives a detailed account of the analysis which has led to the determination of the structure functions P_LL − P_TT/ε and P_LT and the electric and magnetic generalized polarizabilities (GPs) α_E(Q²)and β_M(Q²) at values of the four-momentum transfer squared Q² = 0.92 and 1.76 GeV². These data, together with the results of VCS experiments at lower momenta, help building a coherent picture of the electric and magnetic GPs of the proton over the full measured Q² range and point to their nontrivial behavior.
