9415225 Bordner This award supports a 12-month Japan Society for the Promotion of Science Postdoctoral Fellowship for Dr. Andrew Bordner, Department of Physics, University of Wisconsin, at the University of Kyoto, Japan. Dr. Bordner will work with Dr. Taichiro Kugo in the Department of Physics, on a research project entitled, "Japan JSPS Program: Improved Ladder Approximation to the Bethe-Salpeter Equation." Bordner and Kugo will collaborate on a project using the improved ladder approximation in quantum chromodynamics. In particular, the team will apply the ladder approximation to the prediction of the Isgur-Wise function of heavy quark effective field theory. This function is the only undetermined parameter for semi-leptonic weak decays in the limit where the heavy quark mass is much larger than the binding energy of the quarks in the meson. Professor Kugo developed the ladder approximation and Bordner will work with him on the much needed calculations to further understand the two functions which arise at the next order in the 1/M heavy quark expansion. ***

小行星9415225 该奖项支持日本科学促进会为日本京都大学威斯康星州大学物理系的Andrew Bordner博士提供为期12个月的博士后研究金。 Bordham博士将与物理系的Kugo Taichiro博士合作，开展一项名为“日本JSPS计划：Bethe-Salpeter方程的改进阶梯近似”的研究项目。" Bordham和Kugo将合作一个项目，使用量子色动力学中改进的阶梯近似。 特别是，该团队将应用阶梯近似来预测重夸克有效场论的Isgur-Wise函数。 在重夸克质量远大于介子中夸克的结合能的极限下，这个函数是半轻子弱衰变的唯一待定参数。 Kugo教授开发了阶梯近似，Bornell将与他一起进行急需的计算，以进一步了解在1/M重夸克膨胀中出现的下一个顺序的两个功能。 ***
