Observables in the Decays of B to Two Vector Mesons
Cheng-Wei Chiang, Lincoln Wolfenstein
In general there are nine observables in the decay of a B meson to two vector mesons defined in terms of polarization correlations of these mesons. Only six of these can be detecte…
Bounds on Heavy-to-Heavy Baryonic Form Factors
Cheng-Wei Chiang
Upper and lower bounds are established on the Lambda_b -> Lambda_c semileptonic decay form factors by utilizing inclusive heavy-quark-effective-theory sum rules. These bounds are c…
Bounds on Heavy-to-Heavy Mesonic Form Factors
Cheng-Wei Chiang, Adam K. Leibovich
We provide upper and lower bounds on the form factors for B -> D, D^* by utilizing inclusive heavy quark effective theory sum rules. These bounds are calculated to leading order in…
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^…
