Effective Lagrangian Approach to Weak Radiative Decays of Heavy Hadrons
Hai-Yang Cheng, Chi-Yee Cheung, Guey-Lin Lin +3
Motivated by the observation of the decay by CLEO, we have systematically analyzed the two-body weak radiative decays of bottom and charmed hadrons. There e…
CP Conserving and Violating Contributions to
C. Q. Geng, I. J. Hsu, Y. C. Lin
We study both CP conserving and violating contributions to the decay . We find that the decay branching ratio is dominated by the CP conserving part. In the sta…
Corrections to Chiral Dynamics of Heavy Hadrons: SU(3) Symmetry Breaking, (with some minor corrections)
Hai-Yang Cheng, Chi-Yee Cheung, Guey-Lin Lin +3
In previous publications we have analyzed the strong and electromagnetic decays of heavy mesons and heavy baryons in a formalism which incorporates heavy-quark and chiral symmetrie…
Corrections to Chiral Dynamics of Heavy Hadrons: (I) 1/M Correction
H. Y. Cheng, C. Y. Cheung, G. L. Lin +3
In earlier publications we have analyzed the strong and radiative decays of heavy hadrons in a formalism which incorporates both heavy-quark and chiral symmetries. In particular, w…
Heavy Quark and Chiral Symmetry Predictions for Semileptonic Decays B->D(D*),pi,l,nu
H-Y Cheng, C-Y Cheung, W. Dimm +4
We study in detail the prediction for the semileptonic decays by heavy quark and chiral symmetry. The branching ratio for $\bar{B} \to D π\ell \ba…
Chiral Lagrangians for Radiative Decays of Heavy Hadrons
H. Y. Cheng, C. Y. Cheung, G. L. Lin +3
The radiative decays of heavy mesons and heavy baryons are studied in a formalism which incorporates both the heavy quark symmetry and the chiral symmetry. The chiral Lagrangians f…
