摘要：

The diffractive photon production at large momentum transfer and large energies is a probe of the parton dynamics of the diffractive exchange. In this paper we revisit the leading order Balitsky-Fadin-Kuraev-Lipatov equation approach for this process and estimate, for the first time, the differential and total cross sections considering the next-to-leading order corrections for the Balitsky-Fadin-Kuraev-Lipatov characteristic function. We obtain a reasonable agreement with the DESY-HERA data. DOI: 10.1103/PhysRevD.87.054035
