超弦理论中运动膜与背景无质量场和快子场的相互作用

Interaction of Moving Branes with Background Massless and Tachyon Fields in Superstring Theory

Zahra Rezaei, Davoud Kamani

摘要:

本文利用边界态理论研究了在部分紧致时空中运动的D-$p$ -膜,背景场为:Kalb-Ramond $B_{μν}$,U(1)规范场$A_α$和快子场.边界态使我们能够得到两个膜与上述背景场的相互作用振幅。膜是相互平行或垂直的。背景场的存在、时空某些方向的紧化、膜的运动和膜维数的任意性给了这个系统一个普遍的特征。由于快子场和膜的速度,相互作用振幅的行为显示出明显的不同于传统的。

英文摘要:

Using the boundary state formalism we study a moving D$p$-brane in a partially compact spacetime in the presence of the background fields: Kalb-Ramond $B_{μν}$, a U(1) gauge field $A_α$ and the tachyon field. The boundary state enables us to obtain interaction amplitude of two branes with above background fields. The branes are parallel or perpendicular to each other. Presence of the background fields, compactification of some directions of the spacetime, motion of the branes and arbitrariness of the branes' dimensions give a general feature to the system. Due to the tachyon fields and velocities of the branes, the behavior of the interaction amplitude reveals obvious differences from what is conventional.
