Abstract
As a first step towards the computation of the NLO corrections to the photo n impact factor in the gamma* gamma* --> gamma* gamma* scattering process, we calculate the one loop corrections to the coupling of the Reggeized gluo n to the gamma*-->q (q) over bar vertex. We list the results for the Feynma n diagrams which contribute the following: all loop integrations are carrie d out and the results are presented in the helicity basis of a photon, quar k, and antiquark.
