数值计算胶子单圈振幅

Calculating gluon one-loop amplitudes numerically

Jan-Christopher Winter, Walter T. Giele

摘要:

本文报告了使用广义么正性技术半数值计算单圈振幅的独立实现。该算法以C++代码的形式实现,严格遵循Ellis,Giele,Kunszt和Melnikov的方法。对于胶子的情况下,该算法进行了简要回顾。双精度的结果,证明了这种计算的准确性和效率。

英文摘要:

This note reports on an independent implementation of calculating one-loop amplitudes semi-numerically using generalized unitarity techniques. The algorithm implemented in form of a C++ code closely follows the method by Ellis, Giele, Kunszt and Melnikov. For the case of gluons, the algorithm is briefly reviewed. Double-precision results are presented documenting the accuracy and efficiency of this computation.
