Compendium of bag-model matrix elements of the weak nonleptonic Hamiltonian

Abstract

ABSTRACT: A comprehensive list of baryon and meson single-particle matrix elements of the nonleptonic weak Hamiltonian is presented. Quantum-chromodynamics (QCD) radiative cor rections have had considerable impact on the modern form of the nonleptonic weak Hamiltonian. The first publications on this subject appeared in 1974. In the following six years, the work of Ref. was extended to include both the effect of mass scales associated with heavy quarks' and also ihe occurrence of weak vertices at which color-gluon emission occurs. The latter effect can arise either from the existence of as-yet undetected right-handed currents, ' or from purely left-handed currents, appearing in the dimension-5 operators as induced by QCD radiative corrections.
