چکیده
We review some techniques of resummation applied to heavy quark production in hadronic scattering and electroproduction near partonic threshold, and discuss the reduction of factorization scale dependence in resummed cross sections.

In the calculation of hadronic cross sections in perturbative QCD one factorizes universal parton distributions from hard-scattering factors which are processdependent and in general involve color exchange. The perturbative expansions for several QCD cross sections near partonic threshold include logarithmic terms which can be resummed to all orders in perturbation theory. Here we will discuss ...

In the NRQCD factorization for productions and decays of a quakonium the difference between the quarkonium mass and the twice of the heavy quark mass is neglected. We attempt to interpret the difference in term of NRQCD matrix elements, and consider the effect introduced by the difference in quarkonium decays. The effect is significant in these decays. Similar effect in decays of heavy-flavor h...

The hadroproduction of lepton pairs with mass Q and transverse momentum QT can be described in pertur-bative QCD by the same partonic subprocesses as prompt photon production. We demonstrate that, like prompt photon production, lepton pair production is dominated by quark-gluon scattering in the region QT > Q/2. This leads to sensitivity to the gluon density in kinematical regimes that are acce...

New experiments in polarised deep inelastic scattering will mainly concentrate on the measurement of semi-inclusive asymmetries. Especially, the upgraded HERMES experiment at DESY and the newly build COMPASS experiment at CERN will investigate the gluon polarisation via open charm and high pT hadron pair production , study in detail the flavour decomposition of the quark helicity distributions ...

Explicit quark-hadron duality in the limit of heavy quark mass is studied using the ’t Hooft model, where both partonic and hadronic amplitudes may be computed exactly. Results for weak decays of heavy mesons are presented for both standard spectator decays, where the duality limit is convincingly approached, and annihilation decays of the valence quark-antiquark pair, where the approach to asy...
