One-Long QCD Corrections for Nonleptonic delta S = 0 Weak Hamiltonian in Sic-Quark Models

摘要

Gluon correlations for the weak nonleptonic Hamiltonian with delta S=0 are evaluated with account for heavy quark made masses. Group-theory operator basis has been constructed which enables to use a universal matrix of an anomalous dimension and to obtain compact algebraic expressions for the renormalized Hamiltonian coefficients. An essential dependence of the results upon the choice of electroweak interaction model was demonstrated. A calculated value for pion asymmetry parameter Asub( pi ) proves to be 2.3 in the Kobayashi-Maskawa model and -0.2 in the V-like model. (Atomindex citation 14:763311)
