Charmless Hardronic Decays : Angular Distributions, Direct CP Violation and Determination of the Unitary Triangle
B. Tseng, Cheng-Wei Chiang
Two-body charmless nonleptonic decays of are studied within the generalized factorization approach using a recent calculation of the effective Wilson coefficients $c^…
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 decays are discussed.
Exclusive charmless hadronic decays into and
B. Tseng
Using the next-to-leading order QCD-corrected effective Hamiltonian, charmless exclusive nonleptonic decays of the meson into or are calculated within the generalize…
Solution of sign problem in heavy meson decays: nonfactorizable soft gluons in nonleptonic heavy meson decays
B. Tseng, Hsiang-nan Li
For the first time, a solution to the sign problem in heavy meson decay based on PQCD factorization theorems. The point is to include QCD evolution effort characteristic…
The Decay Revisited
Hai-Yang Cheng, B. Tseng
The $\b$ decay does not receive any nonspectator contributions and hence its theoretical calculation is relatively clean. Two different methods are employed for the study of $\b$.…
