从经典作用量看协变量子超弦和超粒子

The Covariant Quantum Superstring and Superparticle from their Classical Actions

P. A. Grassi, G. Policastro, P. van Nieuwenhuizen

摘要:

我们开发了一种基于Noether方法的方法来构造幂零BRST收费和BRST不变的行动。我们首先将这种方法应用于平空间协变超弦的全纯部分,发现需要我们在前面的工作中手工引入的鬼作用量b,c_z来修正鬼作用量的规范对称性。然后我们将这种方法应用于超粒子,并确定它的上同调。最后,我们将结果推广到超弦的左移和右移扇区。

英文摘要:

We develop an approach based on the Noether method to construct nilpotent BRST charges and BRST-invariant actions. We apply this approach first to the holomorphic part of the flat-space covariant superstring, and we find that the ghosts b, c_z which we introduced by hand in our earlier work, are needed to fix gauge symmetries of the ghost action. Then we apply this technique to the superparticle and determine its cohomology. Finally, we extend our results to the combined left- and right-moving sectors of the superstring.
