QCD corrections to weak decays
Description
Weak decays are significantly altered by effects of strong interaction. In the K system these corrections give rise to ΔI=1/2 rule, and have measurable effects on rare weak process like K→πνanti ν, K→πe+e- and ε'/ε. The situation in the K system is briefly reviewed. Strong interaction effects are also important in D and B system. A possible mechanism for D+-D0 life-time difference is reviewed and then rare B processes are dealt with extensively. Electromagnetic penguin diagrams are enhanced by QCD corrections, giving rise to process like B→K*γ and B→Ke+e-. Process mediated by gluon penguins are also discussed. (orig.)
