摘要：

Exclusive photoproduction of dileptons, gamma N --> l(+)l(-)N, is and will be measured in ultraperipheral collisions at hadron colliders. We demonstrate that the timelike deeply virtual Compton scattering (TCS) mechanism gamma q --> l(+)l(-)q, where the lepton pair comes from the subprocess gamma q --> gamma*q, dominates in some accessible kinematical regions, thus opening a new way to study generalized parton distributions in the nucleon at small skewedness.
