摘要：

The J/?? production originating from elastic and inelastic photoproduction processes in p-p collisions at LHC energies is investigated, where the fragmentation processes are involved. An exact treatment is performed, which adopts the Martin-Ryskin method to weight the contribution from different channels, and can return to Weizs??cker-Williams approximation (WWA) when Q2 ??? 0. The relevant kinematical relations are also achieved. We present a comprehensive analysis for the feature of WWA by comparing with the exact treatment. The results are expressed in Q2, y, z, pT, and yr (rapidity) distributions, and the total cross sections are also estimated. The numerical results indicate that the incoherent-photon emission can provide a meaningful contribution to elastic photoproduction, and starts to play a very important role in the inelastic processes. The photoproduction and fragmentation processes can improve the contribution of J/?? production in p-p collisions at LHC energies. Moreover, the WWA is only effective in very restricted domains, and the exact treatment is needed to deal accurately with the J/?? photoproduction, which can naturally avoid double counting and WWA errors.
