Virtual Compton Scattering from the Proton and the Properties of Nucleon Excited States

Abstract

We calculate the N * contributions to the generalised polarisabilities of the proton in virtual Compton scattering. The following nucleon excitations are included: N * (1535), N * (1650), N * (1520), N * (1700), Δ * (1232), Δ * (1620) and Δ * (1700). The relationship between nucleon structure parameters, N *  properties and the generalised polarisabilities of the proton is illustrated.
