紧致时空中背景无质量场和快子场的运动膜

Moving Branes with Background Massless and Tachyon Fields in the Compact Spacetime

Zahra Rezaei, Davoud Kamani

摘要:

本文将在紧致时空中,在存在Kalb-Ramond场$B_{μν}$、内部U(1)规范场$A_α$和快子场的情况下,得到与运动$Dp$膜有关的边界态。根据这种状态,膜和封闭弦的性质,从它发射的混合边界条件,将得到。利用这个边界态,我们计算了部分紧致时空中两个运动的$Dp_{1}$和$Dp_{2}$ -膜与上述背景场的相互作用振幅。它们相互平行或垂直。将分析相互作用振幅的性质,并提取无质量态对相互作用的贡献。

英文摘要:

In this article we shall obtain the boundary state associated with a moving $Dp$-brane in the presence of the Kalb-Ramond field $B_{μν}$, an internal U(1) gauge field $A_α$ and a tachyon field, in the compact spacetime. According to this state, properties of the brane and a closed string, with mixed boundary conditions emitted from it, will be obtained. Using this boundary state we calculate the interaction amplitude of two moving $Dp_{1}$ and $Dp_{2}$-branes with above background fields in a partially compact spacetime. They are parallel or perpendicular to each other. Properties of the interaction amplitude will be analyzed and contribution of the massless states to the interaction will be extracted.
