论文摘要
我们确定了边界状态，与Kalb-Ramond Field的存在和$ U（1）$规范的潜力相关的是分数D $ p $ brane。背景时空是非紧凑型Orbifold $ \ Mathbb {r}^{1，21} \ otimes \ Mathbb {r}^4/ \ Mathbb {Z} _2 $。此外，勃烷具有横向速度。我们通过两个分数D $ p $ branes与先前的背景字段的相互作用来计算一个无质量封闭串的辐射幅度。麸皮穿着不同的田地，并具有横向运动。将研究总辐射幅度以进行大桥间分离。最后，将明确研究重力，Kalb-Ramond（Axion）和Dilaton排放。我们的计算是在骨弦理论的背景下。
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.
