K factor in two-photon production of hadron jets

A calculation is made of corrections to the hard process γγ→2 jets from the interaction with soft long-wave gluons in the orders α/sub s/ and α2/sub s/. It is shown that the corrections of the type (π2α/sub s/)/sup n/ in these orders tend to be exponentiated into the K factor. The value obtained for the K factor greatly improves the agreement between QCD and the experimental data
