Higher Order Polarizabilities of the Proton
Barry R. Holstein, D. Drechsel, B. Pasquini, M. Vanderhaeghen
Abstract
Compton scattering results are used to probe proton structure via measurement of higher order polarizabilities. Values for αE2p,βE2p,αEνp, βEνp determined via dispersion relations are compared to predictions based upon chiral symmetry and from the constituent quark model. Extensions to spin-polarizabilities are also discussed.
