Deeply virtual Compton scattering amplitude in the parton model — •Madina Penttinen¹, M.V Polyakov¹, A.G. Shuvaev² und M.

We compute the amplitude of deeply virtual Compton scattering in the parton model. We found that the amplitude up to the accuracy O(1/Q) depends on new skewed parton distributions (SPDs). These additional contributions make the DVCS amplitude explicitly transverse.
