摘要:
本文提出了一种计算费曼积分积分部分关系解的1/d展开系数的方法。该方法的核心思想是利用线性替换将这些关系转换为显式的递推形式。对于真空积分的情况,提出了一种可能的替换类型。其适用性在多个家族的无质量(单条质量线)真空积分中得到了验证,最高达到7环水平。
英文摘要:
A method for calculating the $1/d$ expansion coefficients for solutions of integration by parts relations for Feynman integrals is presented. The idea is to use linear substitutions to transform these relations to an explicitly recursive form. A possible type of such substitutions is proposed for the case of vacuum integrals. Its applicability is shown for several families of massless (with one massive line) vacuum integrals up to the 7-loop level.
