一种杂优超弦耦合纤维丛时的标准维数

CRITICAL DIMENSION OF HETEROTIC SUPERSTRING COUPLING FIBER BUNDLE

耦合纤维丛到带Wess—Zumino项的杂优超弦,改进了标准维数的推导方法,得到了较好的结果,且易于扩充到大的N超荷模型。

By means of the tensor multiplication rules of scalar multriplets, the action of the nonlinear a model with a Wess - Zumino term coupling fiber bundle is derived. After treating the manifold of the superstring as a product of d - dimensional Minkowski Space Md with the group manifold G, Md G and using BRST method, we perform the quantization of the model and turn out to get the critical dimension
