有挠pp波超弦的一般算符解和BRST量子化

General Operator Solutions and BRST Quantization of Superstrings in the pp-Wave with Torsion

Yoichi Chizaki, Shigeaki Yahikozawa

摘要:

在pp波背景下,我们完全实现了Ramond-Neveu-Schwarz(RNS)超弦的正则协变量子化,其中NS-NS反对称二型场的通量为非零。这里这个通量等价于一个非零挠率。在这种量子化中,满足整个运动方程和所有正则(反)对易关系的一般算子解起着重要作用。整个协变弦坐标和费米子都可以由自由模组成。利用协变自由模表象,计算了超维拉索罗代数中的反常,并由具有通量的pp波背景中BRST荷的幂零性条件确定了时空的维数和序常数.

英文摘要:

We completely accomplish the canonically covariant quantization of Ramond-Neveu-Schwarz (RNS) superstrings in the pp-wave background with a non-zero flux of the NS-NS antisymmetric two-form field. Here this flux is equivalent to a nonvanishing torsion. In this quantization, general operator solutions, which satisfy the entire equation of motion and all the canonical (anti)commutation relations, play an important role. The whole of covariant string coordinates and fermions can be composed of free modes. Moreover, employing covariant free-mode representations, we calculate the anomaly in the super-Virasoro algebra and determine the number of dimensions of spacetime and the ordering constant from the nilpotency condition of the BRST charge in the pp-wave background with the flux.
