Heavy Quarks at Threshold: Recent Developments
High Energy Physics - Phenomenology
2007-05-23 v1
Abstract
Recent developments in the treatment of a system of heavy quarks close to their production threshold are discussed. Particular emphasis is put on the next-to-next-to-next-to-leading order (NLO) corrections to the energy levels and the wave function and their effect on the cross section . Furthermore, the resummation of logarithmic corrections within the framework of potential non-relativistic QCD (pNRQCD) are considered.
