A. Lazopoulos

摘要:

给出了一个用D_s维么正切割算法计算虚贡献对非线性光学QCD振幅的c++实现。目前的版本包括任意数量的外部胶子,胶子传播子在回路中。构建块是树水平的颜色有序振幅与胶子和胶子和两个标量在五个维度。数值稳定性问题的解决和协议已达成的结果发表在文献中。

英文摘要:

A c++ implementation of the D_s-dimensional unitarity cut algorithm for the numerical evaluation of the virtual contribution to NLO QCD amplitudes is presented. The current version includes an arbitrary number of external gluons with gluonic propagators in the loop. The building blocks are tree level color-ordered amplitudes with gluons and with gluons and two scalars in five dimensions. Numerical stability issues are addressed and agreement has been reached with the results published in the literature.
