Abstract

It is shown that QCD corrections taking into account both collinear and infrared gluons attain a magnitude of the order of 100% in the reaction PP →r γ + X. The value of the K factor is calculated: K∼1.5–1.6 withk T ∼ 10 (GeV/sec)2. Perturbation theory is applicable, since the large constants are exponential and are practically completely taken into account by the K factor.
