Direct CP Violation and Final State Interactions in Hadronic B Decays
Hai-Yang Cheng
Final-state rescattering effects on the hadronic B decays and their impact on direct CP violation are examined. The phenomenology of the polarization anomaly in decays i…
Status of Exclusive Baryonic B Decays
Hai-Yang Cheng
The status of exclusive two-body and three-body baryonic B decays is reviewed. The threshold peaking effect in baryon pair invariant mass is stressed and explained. Weak radiative…
Implications of Recent Measurements of Nonleptonic Charmless B Decays
Hai-Yang Cheng
Implications of recent measurements of hadronic charmless B decays are discussed.
Exclusive Hadronic D Decays to or : Addendum on Resonant Final-State Interactions
Hai-Yang Cheng, B. Tseng
For hadronic two-body decays of charmed mesons involving or , resonance-induced final-state interactions (FSI) that mimic the W-exchange or the W-annihilation topology can…
Factorization Approach for the Rule and in Kaon Decays
Hai-Yang Cheng
The rule and direct CP violation 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 decay amplitudes are studied within the framework of generalized factorization in which the effective Wilson coefficients are gauge-invariant, renormalization-scale an…
