摘要
目的对Polyakov超弦模型进行规范固定参数化。方法采用一种KRR参数化新方法,并结合此模型所具有的κ对称性。结果得到了Polyakov超弦模型的Cartan 1-forms,并能够验证其满足Maurer-Cartan方程。结论这种改进的参数化新方法较之KRR参数化方法计算更为简洁、概念更明确,且能给出与KRR参数化等价的结果,亦能应用于其他背景中的Green-Schwarz超弦模型。
Aim To realize the parameterization of Polyakov's superstring model. Methods A new KRR K-gauge fixed parameterization method is used for Polyakov model, with local K-symmetry taken into account. Results The Cartan 1-forms are given, and Maurer-Cartan equations can be proved. Conclusion The superconformal actions can be simplified dramatically by the new KRR K-gauge fixed parameterized method, and it can give the equivalent results, this method can be used in solving other Green-Schwarz superstring models.
