Loops: Procedures for multiloop calculations in quantum field theory for the reduce system

Abstract
We present a REDUCE package for analitical computation of arbitrary massless, one- and two-loop Feynman diagrams of the propagator type within dimensional regularization. The package calculates Laurent expansions of diagrams in the parameter of dimensional regularization.

Title of program: LOOPS
Catalogue Id: ABJO_v1_0

Nature of problem
Dimensionally regularized multiloop massless Feynman integrals of a propagator type (so called p-integrals), usually appearing in the tasks of the quantum field theory, in particular, high energy physics calculations are computed analytically here.

摘要
我们推出一款基于REDUCE的软件包，可在维数正规化（dimensional regularization）框架下，对传播子型的任意无质量单圈与两圈费曼图（Feynman diagrams）开展解析计算。该软件包能够求解费曼图关于维数正规化参数的洛朗展开（Laurent expansions）。

程序名称：LOOPS
目录编号：ABJO_v1_0

问题属性
本程序针对量子场论（尤其高能物理计算）中常见的传播子型维度正规化无质量多圈费曼积分（亦称p积分（p-integrals））进行解析计算。
