关于R-NS串的另一种量化

On an alternative quantization of R-NS strings

Tsubasa Yuki, Yu Nakayama

摘要:

我们研究R-NS弦论的另一种量子化。在交替量子化中,我们通过交换左移扇区中的产生算符和湮灭算符的作用,定义了左移模和右移模的不同真空。由此产生的弦论只有有限个传播自由度。我们表明,一个适当的选择GSO投影的理论快子自由。该谱与IIA型或IIB型超弦理论的无质量扇区相吻合,没有任何大质量的激发。

英文摘要:

We investigate an alternative quantization of R-NS string theory. In the alternative quantization, we define the distinct vacuum for the left-moving mode and the right-moving mode by exchanging the role of creation operators and annihilation operators in the left-moving sector. The resulting string theory has only a finite number of propagating degrees of freedom. We show that an appropriate choice of the GSO projection makes the theory tachyon free. The spectrum coincides with the massless sector of type IIA or type IIB superstring theory without any massive excitations.
