利用Loop-Tree对偶攻击单圈多支Feynman积分

Attacking One-loop Multi-leg Feynman Integrals with the Loop-Tree Duality

Grigorios Chachamis, Sebastian Buchta, Petros Draggiotis, German Rodrigo

摘要:

我们简要地讨论了循环树对偶(LTD)方法的第一个数值实现。我们应用LTD方法计算紫外和红外有限多支单圈费曼积分。我们攻击标量和张量积分多达六个腿(六边形)。LTD方法显示出独立于外部引脚数量的优异性能。

英文摘要:

We discuss briefly the first numerical implementation of the Loop-Tree Duality (LTD) method. We apply the LTD method in order to calculate ultraviolet and infrared finite multi-leg one-loop Feynman integrals. We attack scalar and tensor integrals with up to six legs (hexagons). The LTD method shows an excellent performance independently of the number of external legs.
