Factorization Approach for the $Δ I = 1/2$ Rule and $ε^{'} / ε$ in Kaon Decays

Hai-Yang Cheng

The $Δ I = 1/2$ rule and direct CP violation $ε^{'} / ε$ in kaon decays are studied within the framework of the effective Hamiltonian approach in conjunction with generalized factorization…

The Delta I=1/2 Rule in Kaon Decays: A New Look

Hai-Yang Cheng

The $K \to π π$ decay amplitudes are studied within the framework of generalized factorization in which the effective Wilson coefficients are gauge-invariant, renormalization-scale an…

Charmless Hadronic Two-Body Decays of B Mesons

Hai-Yang Cheng

A way of circumventing the gauge and infrared problems with effective Wilson coefficients is shown. Implications of experimentally measured charmless $B$ decays are discussed.
