We consider Compton scattering off the proton within a formalism of fixed-$t$ subtracted dispersion relations which can be used to extract the proton polarizabilities from data with a minimum of model dependence. In addition we discuss the possibility to probe the proton structure via the use of higher-order polarizabilities.

Abstract
We consider Compton scattering off the proton within a formalism of fixed-$t$ subtracted dispersion relations which can be used to extract the proton polarizabilities from data with a minimum of model dependence. In addition we discuss the possibility to probe the proton structure via the use of higher-order polarizabilities.File in questo prodotto:
