Description
The purpose of this work is to do a systematic feasibility study of measuring in backward region deeply virtual Compton scattering on the pion in Sullivan processes in the framework of collinear QCD factorization where pion to photon transition distribution amplitudes (TDAs) describes the photon content of the $\pi$ meson. Our approach employs TDAs based on the overlap of light front wave functions, using a previously developed pion light-front wave function and deriving a consistent model for the light front wave functions of the photon. Our results for the TDAs are compared with previous models found in the literature. This work is expected to lead us to an estimate of the cross-sections that could be measured in the future U.S. and China's electron ion colliders, once the computations are completed. It will also provide a comparison with the forward Sullivan DVCS case, for which a strong signal is expected.
