<![CDATA[ My main research interest is the non-perturbative aspects of the strong interaction in elec- troweak physics, using the tools of lattice QCD and effective field theory. In the following few years, I would like to focus on b- and c- quark physics, which enables stringent tests of the Standard Model and the search for new physics via high-precision experimental measurements and theoretical calculations. Specifically, I will work on: ‧ Physics of #3;b baryon: The goal of this project is to calculate the form factors in the #3;b ! #3; and #3;b ! #3;l+l. decays for polarised #3;b. These decay channels are sensitive to new physics involving right-handed couplings. ‧ Physics of B and D mesons: The goal of this project is to enhance the inputs of lattice QCD in CKM physics, and search for new physics via D0 . ¯D0 mixing. These proposed projects will be carried out with physicists in Taiwan, as well as in the USA and the UK. They will involve both analytical and numerical calculations, and will produce results that will be interesting for physics at current and future experiments, such as CLEO, the B factories and the LHC, around the world. ]]>
