Heavy Quark Effective Theory

This up-to-date review also serves as an introduction to Heavy Quark Effective Theory (HQET) - a new approach to heavy quark physics problems in Quantum Chromodynamics (QCD). Heavy quark physics is one of the most active areas of high-energy physics, especially at this time when B-factories at SLAC and KEK are producing high-quality results, and yet other facilities are being developed. HQET has already led to significant progress in our understanding of heavy quark physics during the last ...
