Susycal - Symbolic computations in supersymmetric theories

Abstract
The calculation of supergraphs within the superfield-formalism entails complex expressions and numerous divergent integrals. This is even more so for non-covariant supergauges. SUSYCAL is a package of PASCAL procedures which is able to manipulate formulae and perform these calculations. The algebra of the non-covariant operators of the FD-gauge and the covariant derivatives is included in SUSYCAL as a fixed set of rules. This first version of SUSYCAL to be presented comprises also the (symbol...

Nature of problem
Non-covariant gauges within the superfield formalism have several advantages over the covariant formulation. One of the most famous examples is the Wess-Zumino gauge where the dimensionless field is eliminated by the equations of motion. The algebra of covariant derivates is extended through the introduction of explicit Grassmann variables. This leads in most cases to much more complicated propagators. Using the Feynman rules to evaluate even simple graphs the integrations in superspace becomes ...

摘要
在超场形式主义中，超图的计算涉及复杂的表达式和大量的发散积分。对于非协变超规范而言，情况尤为如此。SUSYCAL是一套PASCAL过程包，能够操作公式并执行这些计算。SUSYCAL中包含了FD规范非协变算符的代数和协变导数的代数，作为一个固定的规则集。本版本首次介绍的SUSYCAL还包括了（符号...

问题性质
在超场形式主义中，非协变规范相对于协变形式具有多个优势。最著名的例子之一是Wess-Zumino规范，其中无量纲场通过运动方程被消除。通过引入显式的Grassmann变量，协变导数的代数得到扩展。这通常导致传播子变得更加复杂。使用费曼规则评估甚至简单的图时，超空间中的积分变得...
