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[subscript LL]−P[subscript TT]/ε and P[subscript LT] and the electric and magnetic generalized polarizabilities (GPs) α[subscript E](Q[superscript 2]) and β[subscript M](Q[superscript 2]) at values of the four-momentum transfer squared Q[superscript 2]=0.92 and 1.76 GeV[superscript 2]. 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 Q[superscript 2] range and point to their nontrivial behavior.
