Quantum-chromodynamic Estimates for Heavy-particle Production (1978) |
|
The associated production of hadrons containing heavy quarks is studied in the framework of a model based on quark-gluon color gauge field theory [quantum chromodynamics (QCD)]. We assume that the dominant mechanism for the production of heavy quarks in real and virtual photon beams is 
where 
denotes a vector gluon and 
an arbitrary heavy quark. For 
, 
. and 
beams we consider the mechanisms 
and 
. The cross sections for the internal subprocesses are calculated at lowest order in the perturbation expansion for QCD. We include a brief discussion of higher-order corrections to our calculation.
