A New Formulation for HQET
Tsung-Wen Yeh
We proposed a new formulation for heavy quark effective theory (HQET), whose Lagrangian is hermitian and has a manifest reparameterization invariance. As an application, we calcula…

PQCD Analysis of Inclusive Semileptonic Decays of A Polarized Lambda_b Baryon
Tsung-Wen Yeh
We investigate the Lambda_b polarization problem in the inclusive semileptonic decays of a polarized Lambda_b baryon, using the modified perturbative QCD formalism which includes S…

On the mass correction of heavy hadrons of arbitrary spin in heavy hadron effective theory
Tsung-Wen Yeh, Chien-er Lee
The mass correction forms of the arbitrary spin heavy hadrons are derived by using the projection operator method. The Bjorken sum rule for finite mass is derived by using the resu…
