Two-photon exchange and elastic scattering of longitudinally polarized electron on polarized deuteron
Abstract
Structure functions and polarization observables in elastic scattering of longitudinally polarized electron on polarized deuteron are considered within approximation of one-photon + two-photon exchange. It is shown that contribution of two-photon exchange in the generalized structure function A is of order of few percent, while in the generalized structure function B it is of order of 10--20 %. We have found that components T_{20} and T_{21} of tensor analyzing power are mainly determined by one-photon exchange, but T_{22} is mainly determined by interference between one-photon exchange and two-photon exchange. We have also considered polarization observables T_{11}, C_{21} and C_{22} which are proportional to imaginary part of the reaction amplitude and vanish in the framework of one-photon exchange.
