Dispersion relation formalism for the two-photon exchange correction to elastic muon–proton scattering: elastic intermediate state
Abstract We evaluate the two-photon exchange correction to the unpolarized cross section in the elastic muon–proton scattering within dispersion relations. One of the six independent invariant amplitudes requires a subtraction. We fix the subtraction function to the model estimate of the full two-ph...
