Exclusive photoproduction of dileptons, Ξ³p β + -p, will be measured in ultraperipheral collisions at LHC. The mechanism where the lepton pair comes from a heavy timelike photon radiated from a quark interferes with the pure QED process Ξ³Ξ³ β + -. As an analog of deeply virtual Compton scattering, thi
