具有横向运动的分数缀饰D $p$ -膜的闭弦辐射

Closed String Radiation from the Interacting Fractional-Dressed D$p$-Branes with the Transverse Motions

Hamidreza Daniali, Davoud Kamani

摘要:

我们确定了在Kalb-Ramond场和$U(1)$规范势存在的情况下与分数D $p$ -膜相关的边界态。背景时空是非紧轨道$ \mathbb{R}^{1, 21} \otimes \mathbb{R}^4/ \mathbb{Z}_2$。此外,膜有横向速度。我们从两个分数D $p$ -膜与先前背景场的相互作用中计算了无质量闭弦的辐射振幅。这些膜被不同的场修饰过,并且有横向运动。将研究大膜间分离的总辐射振幅。最后,将分别研究引力子、Kalb-Ramond(轴子)和介子发射。我们的计算是在玻色子弦论的背景下进行的。

英文摘要:

We determine the boundary states, associated with a fractional D$p$-brane in the presence of the Kalb-Ramond field and a $U(1)$ gauge potential. The background spacetime is the non-compact orbifold $ \mathbb{R}^{1, 21} \otimes \mathbb{R}^4/ \mathbb{Z}_2$. Besides, the brane has a transverse velocity. We compute the radiation amplitude of a massless closed string from the interaction of two fractional D$p$-branes with the previous background fields. The branes have been dressed by different fields and have transverse motions. The total radiation amplitude will be investigated for large inter-brane separation. Finally, the graviton, Kalb-Ramond (axion) and dilaton emissions will be distinctly studied. Our calculations are in the context of the bosonic string theory.
