On timelike and spacelike deeply virtual Compton scattering at next to leading order

Abstract: We emphasize how large O(α s ) corrections to timelike and spacelike virtual Compton scattering amplitudes are in the generalized Bjorken scaling regime, and in particular the gluonic contributions, even in the medium energy range which will be studied intensely at JLab12 and in the COMPASS-II experiment at CERN. We stress that the timelike and spacelike cases are complementary and that their difference deserves much special attention.

Double logarithms resummation has been much studied in inclusive as well as exclusive processes. The Sudakov mechanism has often be the crucial tool to exponentiate potentially large contributions to amplitudes or crosssections near phase-space boundaries. We report on a recent work where a very different pattern emerges : the DVCS quark coefficient function C q (x,ξ ) develops near the particular point x = ξ a non-alternate series in α s n 2nlog (x − ξ ) which may be resummed in a cosh [K α s log(x − ξ )] factor. This result is at odds with the known result for the corresponding coefficient function for the pion transition form factor near the end point C q (z) although they are much related through a z → x / ξ correspondence.

Timelike and spacelike virtual Compton scattering in the generalized Bjorken scaling regime are complementary tools to access generalized parton distributions. We stress that the gluonic contributions are by no means negligible, even in the medium energy range which will be studied intensely at JLab12 and in the COMPASS-II experiment at CERN. Ultraperipheral collisions with proton or ion beams may also be used at RHIC and at collider or fixed target experiments at LHC.
