一般有质量情形下单圈N点函数的稳定一维积分表示:I -三点函数

Stable One-Dimensional Integral Representations of One-Loop N-Point Functions in the General Massive Case: I - Three Point Functions

J. Ph. Guillet, E. Pilon, M. Rodgers, M. S. Zidi

摘要:

在这篇文章中,我们提供的表示单圈三点函数在4和6维的一般情况下与复杂的质量。后者是GOLEM库的一部分,用于计算单回路多腿振幅。这些表示是一维积分的设计是免费的不稳定性引起的反权力的革兰氏行列式,因此适合稳定的数值实现。

英文摘要:

In this article we provide representations for the one-loop three point functions in 4 and 6 dimensions in the general case with complex masses. The latter are part of the GOLEM library used for the computation of one-loop multileg amplitudes. These representations are one-dimensional integrals designed to be free of instabilites induced by inverse powers of Gram determinants, therefore suitable for stable numerical implementations.
