摘要:
The QCD O(&agr;2s) corrections to large‐pTreal photon production from scattering in the quark‐gluon channel are studied in the soft gluon limit. In this limit we carefully preserve the analytic structure of amplitudes in the small momenta integration regions. The result is a rather large constant correction to the Born term, or K factor, which significantly improves the agreement with data on p+p → &ggr;+X. The relevance of large corrections in other processes is discussed and the dominant terms of the 0(&agr;2s) corrections to e+e− → 3 jets are reproduced.
