Search for evidence of two-photon exchange in new experimental high momentum transfer data on electron deuteron elastic scattering - art. no. 042202

The possible contribution of two-photon exchange to electron deuteron elast ic scattering at relatively high momentum transfer is discussed. This study was motivated by the high precision data recently obtained at the Jefferso n Laboratory. Using general arguments, based on crossing symmetry for the p rocesses e(-) + h --> e(-) + h and e(+) + e(-) --> h + (h) over bar, we fin d a parametrization for the angular dependence of the interference between the one- and two-photon exchanges in the differential cross section for ela stic ed scattering in terms of a new kinematical variable and compare our f indings to the recent data.
