Running of the heavy quark production current and 1/|k| potential in QCD
The 1/|k| contribution to the heavy quark potential is first generated at one loop order in QCD. We compute the two loop anomalous dimension for this potential, and find that the renormalization group running is significant. The next-to-leading-log coefficient for the heavy quark production current near threshold is determined. The velocity renormalization group result reproduces the αs ln (αs)...
متن کاملHeavy Quark Production Processes in Qcd*
We discuss two novel QCD effecte which enhance the production of heavy quarks and supersymmetric hadrons beyond that conventionally expected from gluon fusion.

متن کاملCurrent Issues in Heavy Quark Production
Consider the effect of a charm quark (with mass m) being produced in neutral current DIS. For simplicity we concentrate on virtual photon exchange and neglect the bottom quark. Precise data are now available on F2(x,Q ). In pQCD the operator product expansion and asymptotic freedom allow one to calculate the scaling violations. This is incorporated in the factorization theorem where short dista...

متن کاملHeavy quark production in the semihard QCD approach at THERA
In the framework of the semihard (kT factorization) QCD approach, we consider the photoproduction of D mesons associated with two hadron jets and the D production in DIS at THERA conditions with the emphasis on the BFKL and CCFM dynamics of gluon distributions. In the photoproduction of D mesons the attention is focused on the variable xγ , which is the fraction of the photon momentum contribut...
