报告摘要:QCD aspects of exclusive heavy-hadron decays will be discussed with an emphasis on the perturbative factorization properties for the resulting hadronic matrix elements in the heavy quark expansion and on the systematic discussions of the distinct dynamical mechanisms governing the flavor-changing form factors beyond the leading-power approximation. Phenomenological implications of the technical improvements for evaluating the heavy hadron decay amplitudes will be further elaborated with a number of interesting exclusive processes accessible at the LHCb and Belle II experiments.
个人简介:Prof. Yu-Ming Wang earned his PhD degree in physics from the Institute of High Energy Physics, CAS in 2009. Afterwards, he pursued his academic career at University of Siegen, Technical University of Munich, and University of Vienna as a postdoctoral researcher. He joined Nankai University as a full professor in 2016. Prof. Wang has been working on a variety of topics on the theoretical high energy physics, including Heavy Quark Physics and CP Violation, QCD Factorization, Radiative Corrections and Resummation Techniques, QCD Sum Rules, Light-Cone Distribution Amplitudes, Heavy-Quark Effective Theory and Soft-Collinear Effective Theory. His major scientific achievements in heavy quark physics and QCD are widely recognized among the world-class experts, by virtue of the influential works on identifying the eigenfunctions of the Lange-Neubert evolution kernel for the HQET B-meson distribution amplitude, on the first-ever calculation of the non-factorizable charm-loop effect in FCNC B-meson decays, on the systematic formulation of the subleading power corrections to the radiative B-meson form factors, on the rigorous incorporation of light-cone sum rules in the SCET framework, and last but not least on accomplishing the two-loop computation of the key exclusive process of the photon-pion form factor for the first time.
