QCD Corrections to Photon Production in Association with Hadrons in $e^{+}{e}^{-}$ Annihilation

Zoltan Kunszt, Zoltán Trócsányi

A detailed investigation of the theoretical ambiguities present in the QCD description of photon production in $e^{+}{e}^{-}$ annihilation is given. It is pointed out that in a well-defi…
