标题： The Baryon Junction and String Interactions

摘要： 我们研究了禁闭弦之间的连接点。 我们表明，这类连接点的有效理论非常具有预测性，仅有一个新的参数——连接点的质量——控制着系统尺寸展开式中的前几项。 通过开-闭弦对偶性，这些关于重子连接点的考虑映射到了闭合弦的相互作用顶点。 因此，我们在诸如杨-米尔斯理论之类的理论中计算了闭合弦的相互作用顶点。 我们发现了一些三维空间中的弦相互作用令人惊讶的选择规则。 要求微扰稳定性且弦耦合较弱时，我们提出了对连接点质量的约束。 显示英文摘要

摘要： We study junctions between confining strings. We show that the effective theory of such junctions is very predictive with only one new parameter, the junction's mass, controlling the first couple of terms in the expansion in the system size. By open-closed duality these considerations about the baryon junction map to interaction vertices of closed strings. Therefore, we calculate the interaction vertices of closed strings in theories such as Yang-Mills theory. We find some surprising selection rules for string interactions in 3+1 dimensions. Requiring perturbative stability and that the string coupling is weak, we suggest constraints on the junction's mass.
