超对称西格玛模型的伪对偶性

Pseudoduality in Supersymmetric Sigma Models

Mustafa Sarisaman

摘要:

研究了超对称西格玛模型中的伪对偶变换。将伪对偶变换的经典构造推广到超对称情形。我们用流形M上的分量展开方法和流形SO(M)上的正交上标架方法来实现这一点。分量展开法得到的结果是伪对偶变换不是在所有点都可逆的,而是从一个流形上的所有点到第二个流形上黎曼法坐标有效的一个点都发生。西格玛模型在M上的挠率必为零,而在伪对偶流形上的挠率必为非零,且流形的曲率必为常数且相同。在超WZW西格玛模型的情况下,伪对偶方程导致三种不同的伪对偶条件:平坦空间,手征和反手征伪对偶。

英文摘要:

We study the pseudoduality transformation in supersymmetric sigma models. We generalize the classical construction of pseudoduality transformation to supersymmetric case. We perform this both by component expansion method on manifold M and by orthonormal coframe method on manifold SO(M). The component expansion method yields the result that pseudoduality tranformation is not invertible at all points and occurs from all points on one manifold to only one point where riemann normal coordinates are valid on the second manifold. Torsion of the sigma model on M must vanish while it is nonvanishing on pseudodual manifold, and curvatures of the manifolds must be constant and the same. In case of super WZW sigma models pseudoduality equations result in three different pseudoduality conditions; flat space, chiral and antichiral pseudoduality.
