Quark- and Gluon-Condensate Contributions to Penguin Four-Fermi Operators

High Energy Physics - Phenomenology 2009-10-31 v1

Abstract

The nonperturbative content of the QCD vacuum permits the occurrence of QCD-vaccum condensate contributions to penguin amplitudes. We calculate the dimension-4 <mqqˉq><m_q\bar qq> and <αsG2><\alpha_s G^2> contributions to the effective Wilson coefficients for penguin four-Fermi operators, and discuss how such contributions may contribute to nonleptonic B decays.
