Ninja: Automated integrand reduction via Laurent expansion for one-loop amplitudes

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present the public C++ library Ninja, which implements the Integrand Reduction via Laurent Expansion method for the computation of one-loop integrals. The algorithm is suited for applications to complex one-loop processes. Title of program: Ninja Catalogue Id: AETO_v1_0 Nature of problem Computation of one-loop integrals contributing to scattering amplitudes. Versions of this program held in the CPC repository in Mendeley Data AETO_v1_0; Ninja; 10.1016/j.cpc.2014.06.017本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2018）。 摘要 我们发布了公开C++库Ninja，其实现了用于单圈积分（one-loop integrals）计算的洛朗展开被积函数约化法（Integrand Reduction via Laurent Expansion），该算法适配复杂单圈过程的相关应用。 程序名称：Ninja 目录编号：AETO_v1_0 问题性质 计算散射振幅（scattering amplitudes）所需的单圈积分。 存储于Mendeley数据平台CPC库中的本程序版本： AETO_v1_0；Ninja；10.1016/j.cpc.2014.06.017
