Sažetak
The exclusive processes play a vital role in improving our understanding of strong interactions. One important progress in this respect is that perturbative QCD was proposed for exclusive processes involving large momentum transfer. Despite the large number of predictions obtained within proposed framework at the leading order, the question when momentum transfer is large enough to validate pQCD is still open. To big extent, answer to that question is related to the size of higher order corrections. Unfortunately, the list of the exclusive processes analyzed at next-to-leading order is very short. In this talk, predictions for the process gamma gamma -> M^+ M^- (M=pi, K) at the next-to-leading order are presented and accordingly applicability of pQCD at available energies is discussed.
