Diquarks, QCD sum rules, and weak decays

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We determine the “diquark decay constant” from consistency conditions with QCD sum rules. A large numerical value is obtained. The implications are discussed and the diquark picture is applied to weak baryon decays. The results show the importance of the strong quark-quark interaction for weak decays at low energies.
