*****************************************************************

Professor Hsiang-nan Li (Institute of Physics, Academia Sinica, Taiwan) is the winner of the 2007 Achievement in Asia Award (AAA) of the Overseas Chinese Physics Association (OCPA).

The OCPA AAA Award is given annually to Chinese physicists working in Asia in recognition of their outstanding achievements in physics. It carries a total prize of

US $1,500 and a certificate citing the awardee's accomplishments in research.

Professor Hsiang-nan Li received his B.S. degree in physics in 1986 at National Taiwan University and his Ph.D. degree in 1992 at SUNY at Stony Brook. He spent one year at Academia Sinica as a Postdoctoral Fellow and became Associate Professor at National

Chung-Cheng University in 1993. Prof. Li was promoted to professorship in 1997 at National Cheng-Kung University and returned to the Academia Sinica in 2001 as a Research Fellow

Professor Li’s research has been in the area of B physics, especially on exclusive B meson decay. Through B decay, the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements can be calculated and the phases of them would account for the sources of CP violation. The most significant contribution Prof. Li has made is that he developed the perturbative Quantum Chromodynamics (PQCD) approach to exclusive B meson decay. Prof. Li and his colleagues proved that the naive factorization of simple QCD provides only order-of-magnitude estimation, and misses some important mechanism. His calculation included the spectator contribution, as a subleading correction to the simple-minded assumption, and predicted in 2000 a large and negative direct CP asymmetry in the B meson decay. Such a prediction was confirmed by experimental results from both BABAR and BELLE in 2003. With additional data, more and more PQCD predictions for branching ratios and direct asymmetries were confirmed. The PQCD approach, adopted by Prof. Li, has proven to be capable of gaining control of QCD dynamics in exclusive B meson decays, which helps extracting the standard-model parameters and/or revealing (possible) new physics signals.

Prof. Li has served in the International Advisory Committee of JLAB and KIAS and is currently the Chairman of the Physics Division Panel of the National Science Council of Taiwan.

The winner of OCPA's 2007 AAA Award was selected by the following panel of
