束缚规范理论中的重子

Baryonium in Confining Gauge Theories

Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura, Fumihiko Toyoda

摘要:

我们给出了一类新的D5膜的嵌入解,它包裹在AdS ${}_5\times S^5$时空中的$S^5$上,包含基本弦作为U(1)通量,形成重子顶点.这里给出的新解不同于重子顶点,因为它是由$S^5$的两个同侧(南或北)极作为尖点组成的,它们放在我们三维空间的不同点上。这意味着在每个尖点处存在相同大小的电位移,但由于通量数守恒,它们的方向相反。因此,这种组态被认为是D5- $\bar{D5}$束缚态,我们提出这是重子态的顶点,重子态由重子和反重子组成。通过在这个顶点的两个尖点上附加夸克和反夸克,就有可能构造出一个真实的重子素。

英文摘要:

We show a new class of embedding solutions of D5 brane, which wraps on $S^5$ in the AdS${}_5\times S^5$ space-time and contains fundamental strings as U(1) flux to form a baryon vertex. The new solution given here is different from the baryon vertex since it consists of two same side (north or south) poles of $S^5$ as cusps, which are put on different points in our three dimensional space. This implies that the same magnitude of electric displacement exists at each cusp, but their orientations are opposite due to the flux number conservation. This configuration is therefore regarded as a D5-$\bar{D5}$ bound state, and we propose this as the vertex of a baryonium state, which is made of a baryon and an anti-baryon. By attaching quarks and anti-quarks to the two cusps of this vertex, it is possible to construct a realistic baryonium.
