Contribution
It introduces simple technical methods for calculating QCD quantities at order 1/eta_0 and discusses their applications in heavy quark physics and beyond.
Findings
Methods for calculating at order 1/β₀ demonstrated
Examples from heavy quark physics analyzed
QCD results based on renormalization group discussed
Abstract
The large-beta_0 limit of QCD is discussed, with the emphasize on simple technical methods of calculating various quantities at the order 1/\beta_0. Many examples, mainly from heavy quark physics, are considered. Some QCD results based on renormalization group (and not restricted to the large-\beta_0 limit) are also discussed.
