L. Magnea et E. Maina, QCD CORRECTIONS TO THE PRODUCTION OF A HEAVY-QUARK PAIR PLUS A HARD PHOTON IN E(-) ANNIHILATION()E(), Physics letters. Section B, 385(1-4), 1996, pp. 395-403
We present complete results for the O(alpha(s)) corrections to the pro
duction of a heavy quark pair plus a hard photon, in e(+)e(-) annihila
tion, including both photon and Z intermediate states. Virtual correct
ions are calculated analytically in 4 - 2 epsilon dimensions, together
with the soft approximation to the real emission diagrams. After canc
ellation of infrared divergences, real and virtual contributions are c
ombined numerically to obtain the cross section for the production of
two heavy quark jets plus a hard photon in next-to-leading order. The
resulting fully differential cross section can be used to construct ar
bitrary distributions with the desired experimental cuts.
