标题： The Baryon Junction and String Interactions

摘要： 我们研究约束弦之间的接合处。 我们表明，这种接合处的有效理论非常具有预测性，只有一个新的参数，即接合处的质量，控制着系统尺寸展开中的前几项。 通过开-闭对偶性，关于重子接合处的这些考虑映射到闭弦的相互作用顶点。 因此，我们在诸如杨-米尔斯理论等理论中计算闭弦的相互作用顶点。 我们在3+1维中发现了一些关于弦相互作用的令人惊讶的选择规则。 要求微扰稳定性且弦耦合较弱，我们提出了对接合处质量的约束。 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.
