0-图中Neveu-Schwarz弦的无鬼定理

No-Ghost Theorem for Neveu-Schwarz String in 0-Picture

Maiko Kohriki, Hiroshi Kunitomo, Masaki Murata

摘要:

在0-图中直接证明了Neveu-Schwarz弦的无鬼定理。证实了0-图像中的物理状态与常规(-1)-图像中的物理状态之间的一一对应关系。它表明,一个非平凡的度量一致的BRST上同调需要定义一个半正定范数的物理希尔伯特空间。作为副产品,我们找到了一个新的逆图像改变操作,这是非协变的,但与自身的非奇异的操作产品。讨论了构造一种新的规范不变超弦场论的可能性。

英文摘要:

The no-ghost theorem for Neveu-Schwarz string is directly proved in 0-picture. The one-to-one correspondence between physical states in 0-picture and those in the conventional (-1)-picture are confirmed. It is shown that a non-trivial metric consistent with the BRST cohomology is needed to define a positive semi-definite norm in the physical Hilbert space. As a by-product, we find a new inverse picture changing operator, which is non-covariant but has non-singular operator product with itself. A possibility to construct a new gauge invariant superstring field theory is discussed.
