论文摘要
具有任意自能量插入和任意残留能量的单环HQET顶点图的微分方程将减少到$ \ varepsilon $形式，并用于以Goncharov Polylogarithms的形式获得$ \ varepsilon $扩展。
Differential equations for the one-loop HQET vertex diagram with arbitrary self-energy insertions and arbitrary residual energies are reduced to the $\varepsilon$ form and used to obtain the $\varepsilon$ expansion in terms of Goncharov polylogarithms.
