A new method for computing one-loop integrals

Abstract
We present a new program package for calculating one-loop Feynman integrals, based on a new method avoiding Feynman parametrization and the contraction due to Passarino and Veltman. The package is calculating one-, two- and three-point functions both algebraically and numerically to all tensor cases. This program is written as a package for Maple. An additional Mathematica version is planned later.

Title of program: ONELOOP.MA
Catalogue Id: ACVW_v1_0

Nature of problem
The theoretical determination of cross sections in particle processes requires the calculation of radiative corrections. The most important contribution comes from the level of one-loop Feynman diagrams which arise from the model under consideration, usually the standard model of elementary particles.

本报告介绍了一种新型的计算一阶费曼积分的程序包，该程序包基于一种新的方法，该方法避开了费曼参数化以及帕萨里诺-维尔特曼收缩。该程序包能够对一、二、三点函数进行代数和数值计算，涵盖所有张量情况。该程序以 Maple 的程序包形式编写，未来计划开发 Mathematica 版本。程序名称：ONELOOP.MA，目录编号：ACVW_v1_0。

问题性质
粒子过程中截面理论的确立需要计算辐射修正。其中最重要的贡献来自于由所考虑的模型（通常为标准模型）产生的一阶费曼图。
