Automated one-loop calculations: a proof of concept

A. van Hameren, C. G. Papadopoulos, R. Pittau

摘要:

本文提出了一种基于量子化约化方法的算法,可自动计算任意单圈振幅,适用于所有的粒子动量、颜色和螺旋度组态。它已被实施使用的树阶矩阵元素代码HELAC和减少代码CutTools。作为当前实施的潜力的展示,介绍了2007年Les Houches LHC愿望清单中包括的所有子过程的结果。

英文摘要:

An algorithm, based on the OPP reduction method, to automatically compute any one-loop amplitude, for all momentum, color and helicity configurations of the external particles, is presented. It has been implemented using the tree-order matrix element code HELAC and the OPP reduction code CutTools. As a demonstration of the potential of the current implementation, results for all sub-processes included in the 2007 Les Houches wish list for LHC, are presented.
