超引力产生的类电子偶态

Positronium-like states from supergravity

Eoin Ó Colgáin, Hossein Yavartanoo

摘要:

我们研究半经典旋转开弦终止于一个探测Dp-膜上,该膜接近一堆极值、非极值Dp-膜和具有$B$ -场的Dp-膜。在$SU(N+1) \to SU(N) \times U(1)$理论中,这些态可以解释为自旋W玻色子的类正电子素束缚态。在每种情况下,我们描述的字符串的行为和检查之间的关系的能量和角动量的束缚态。

英文摘要:

We study semi-classical rotating open strings ending on a probe Dp-brane close to a stack of extremal, non-extremal Dp-branes and Dp-branes with $B$-fields. These states may be interpreted as positronium-like bound states of spinning W-bosons in an $SU(N+1) \to SU(N) \times U(1)$ theory. In each case, we describe the behaviour of the strings and examine the relation between the energy and the angular momentum of the bound state.
