Weak Decays of Heavy Quarks [PDF]
, 2000 We review some aspects of weak decays of hadrons containing one heavy quark. The main emphasis is on $B$ physics, in particular in the framework of the Heavy Quark Effective Theory.Comment: LaTex, 48 pages, 4 figures; uses psfig, sprocl.sty.

A self-consistent framework of topological amplitude and its SU(N) decomposition
Journal of High Energy Physics, 2021 We propose a systematic theoretical framework for the topological amplitudes of the heavy meson decays and their SU(N) decomposition. In the framework, the topologies are expressed in invariant tensors and classified into tree- and penguin-operator ...

On the short distance nonperturbative corrections in heavy quark expansion [PDF]
, 2000 We study the corrections due to renormalons to the heavy hadron decay width.The renormalons contribution estimated in terms of finite gluon mass based on the assumption that the gluon mass represents the short distance nonperturbative effects in the ...

Non-perturbatively determined relativistic heavy quark action [PDF]
, 2005 Preliminary results are presented in a step scaling determination of the coefficients in the relativistic heavy quark action. By matching finite volume, heavy-heavy and heavy-light meson masses, we attempt to determine the four parameters ($m$, $\zeta$, $

Charm and beauty of the Large Hadron Collider [PDF]
, 2005 With the acceleration of lead nuclei in the LHC, heavy-ion physics will enter a new energy domain. One of the main novelties introduced by the 30-fold energy-jump from RHIC to the LHC is the abundant heavy-quark production.

STAR highlights on heavy ion physics
EPJ Web of Conferences, 2015 RHIC-STAR is a mid-rapidity collider experiment for studying high energy nuclear collisions. The main physics goals of STAR experiment are 1) studying the properties of the strongly coupled Quark Gluon Plasma 2) explore the QCD phase diagram structure ...

From topological amplitude to rescattering dynamics
Journal of High Energy Physics, 2022 We proposed a theoretical framework to correlate the topological diagram at quark level and rescattering dynamics at hadron level. In the framework, both the hadronic triangle diagram, and the topological-scattering diagram, which is the intermediate ...

Semileptonic B Decays from an NRQCD/D234 Action [PDF]
, 2002 Semileptonic B decays are studied on quenched anisotropic lattices using Symanzik improved glue, NRQCD heavy quark and D234 light quark actions. We employ constrained fits to extract ground state contributions to two- and three-point correlators. Results
