Effective Lagrangian due to heavy quarks in quantum chromodynamics

Journal Article · · Phys. Rev., D; (United States)
We extend our previous analysis of heavy-particle effects in the low-energy light-particle sector to quantum chromodynamics. The central technique is the use of the Ward-Takahashi identities due to Becchi-Rouet-Stora transformations. Some discussion of the isolation of mass singularities is given. An important result in our approach, as before, is to give precise meaning to the notion of an effective Lagrangian (which is renormalized) with calculable effective coupling constants. The counterterms for the effective local vertices in the Lagrangian are self-generated by the theory, while the effective coupling constants obey a set of Callan-Symanzik-type equations.
