Heavy-Quark Masses

  • Matthias Neubert
Part of the NATO ASI Series book series (NSSB, volume 363)

Abstract

These lectures provide an introduction to the heavy-quark effective theory and the 1/m Q expansion, which provide the modern framework for a systematic, model-independent description of the properties and decays of hadrons containing a heavy quark. I discuss the applications of these concepts to spectroscopy and to the weak decays of B mesons.

Despite the title of my lectures, I will have to say little about the numerical values of heavy-quark masses. Instead, I will discuss how the fact these masses are large compared with the scale of non-perturbative strong-interaction effects helps to analyze much of the physics of hadrons containing a heavy quark in a model-independent way. In the course of this discussion, it will become apparent that our ability to understand heavy-flavour physics resides on the observation that heavy quarks are so heavy that their masses become irrelevant. Therefore, a better title for my lectures would have been: “Heavy-quark effective theory, and how to get rid of heavy-quark masses”.
