论文摘要
具有通用传播器功率的无壳无质量六点双重框和具有通用传播功率的六边形共形feynman积分以广义号角类型的多个超测量系列的线性组合表示。这些结果来自从其双重共形Feynman参数表示的9倍Mellin-Barnes表示。提出的表达式中的单个术语满足了$ d $ dimensions中的双重盒子的微分方程与$ d+2 $尺寸的六角形。
The off-shell massless six-point double box and hexagon conformal Feynman integrals with generic propagator powers are expressed in terms of linear combinations of multiple hypergeometric series of the generalized Horn type. These results are derived from 9-fold Mellin-Barnes representations obtained from their dual conformal Feynman parameter representations. The individual terms in the presented expressions satisfy the differential equation that relates the double box in $D$ dimensions to the hexagon in $D+2$ dimensions.
