Abstract
- A phenomenological model is employed to treat the rare decays of mesons with neutrino-antineutrino pair production or charged lepton-antilepton production. The model takes advantage of the fact that inside the hadrons, quarks and antiquarks are tightly bound, and they behave like free particles. As such, the rare decay process can be described in terms of the corresponding quark-level decay process, but with the quarks developing ‘dressed’ masses because of QCD effects. The ‘dressed’ quark masses are estimated from the weak decays of the hadrons. With this set of ‘dressed’ quark masses, a reasonable description of the rare decays of the K and B mesons is obtained.
