平面波背景下开弦的非对产生

No pair production of open strings in a plane-wave background

Makoto Sakaguchi, Hyeonjoon Shin, Kentaroh Yoshida

摘要:

我们考虑在IIA型平面波背景下,外加电场是否会引起开弦的电子对产生。在超弦理论的Green-Schwarz表述中,利用光锥规范构造了具有凝聚的D-膜的边界态。圆柱图是用大量的θ函数计算的。虽然电场的值受上限值的限制,但振幅中没有极点,这表明在平面波背景中没有产生对。这一结果对于一类平面波背景是普遍的。

英文摘要:

We consider whether an external electric field may cause the pair production of open strings in a type IIA plane-wave background. The boundary states of D-branes with condensates are constructed in the Green-Schwarz formulation of superstring theory with the light-cone gauge. The cylinder diagrams are computed with massive theta functions. Although the value of the electric field is bounded by the upper value, there is no pole in the amplitudes and it indicates that no pair production occurs in the plane-wave background. This result would be universal for a class of plane-wave backgrounds.
