Soft anomalous dimension matrices in heavy quark-antiquark hadroproduction in association with a gluon jet
Abstract
We compute the soft anomalous dimension (SAD) matrices for production of massive quarks Q and Q in association with a gluon jet, from massless quarks q and antiquarks q: qq→ QQg, and in the gluon scattering gg→ QQg. To analyze the behaviour of the eigenvalues of SAD matrices we perform numerical studies of their eigensystems at two special kinematical configurations.
