Strong CP in Heavy Quark Physics
Communications in Theoretical Physics, 1991We argue that strong CP phase should be shifted to b and t quark masses due to the requirement of vacuum stability. The strong CP problem in low energy sector thus disappears. We predict large CP violation in electric dipole moment of W and heavy quarks.

Aspects of Heavy Quark Physics
1998We discuss the use of two QCD based effective field theories in determining parameters of the standard model. Heavy Quark Effective theory provides a framework for studying the weak decays of the B meson. We calculate the B → Xclv decay rate to second nonvanishing order in the HQET expansion and compare the theoretical prediction to experimental data ...

Heavy Quark Physics on Large Lattices
2005We describe our recently initiated project for the non-perturbative study of heavy quark systems in quenched lattice QCD. Motivated by the desire to avoid additional approximations, we work on fine lattices which are large in terms of the number of lattice points.

1997
Heavy Quark Effective Theory (HQET) is reviewed and applied to extracting the fundamental parameters of the Standard Model from experimental data. The main focus is on precision measurements of the Cabibbo-Kobayashi-Maskawa matrix element |Vcb|, and the charm and bottom quark masses mc and mb.
