非微扰重夸克有效理论在半轻子B衰变中的应用

Non-perturbative Heavy Quark Effective Theory: An application to semi-leptonic B-decays

Michele Della Morte, Jochen Heitger, Hubert Simma, Rainer Sommer

摘要:

我们回顾了一种格子策略,如何非微扰地确定重-轻轴流和矢量流的所有分量的HQET展开中的系数,包括1/m_h-校正。我们还讨论了最近的初步结果的形状因子参数化的半轻子B衰变在领先的顺序在1/m_h。

英文摘要:

We review a lattice strategy how to non-perturbatively determine the coefficients in the HQET expansion of all components of the heavy-light axial and vector currents, including 1/m_h-corrections. We also discuss recent preliminary results on the form factors parameterizing semi-leptonic B-decays at the leading order in 1/m_h.
