夸克-强子连续性是一种强子物质与夸克物质之间没有相变的交叉，基于两相的对称性和激发的匹配。在一个轻奇异夸克质量的极限下，它连接了超子物质和颜色-风味锁定（CFL）相，表现出颜色超导性。最近，有人提出在超流体涡旋穿透两相的情况下可以推广这一猜想[arXiv:1803.05115]，并提出超子物质中的一个强子超流体涡旋可以连接到CFL相中的一个非阿贝尔涡旋（彩色磁通管）。在这里，我们认为，他们的建议是一致的，只有在大距离；相反，我们证明了三个强子超流体漩涡必须与三个不同颜色的非阿贝尔漩涡结合，并且总彩色磁通量被抵消，其中的结称为彩色boojum。我们在基于金兹堡-朗道描述的宏观理论中严格证明了这一点，其中对称性和激发匹配（包括涡旋核心），以及在微观理论中，夸克在涡旋周围的Aharonov-Bohm相匹配。
Quark-hadron continuity was proposed as a crossover between hadronic matter and quark matter without a phase transition, based on the matching of the symmetries and excitations in both phases. In the limit of a light strange-quark mass, it connects hyperon matter and the color-flavor-locked (CFL) phase exhibiting color superconductivity. Recently, it was proposed that this conjecture could be generalized in the presence of superfluid vortices penetrating both phases [arXiv:1803.05115], and it was suggested that one hadronic superfluid vortex in hyperon matter could be connected to one non-Abelian vortex (color magnetic flux tube) in the CFL phase. Here, we argue that their proposal is consistent only at large distances; instead, we show that three hadronic superfluid vortices must combine with three non-Abelian vortices with different colors with the total color magnetic fluxes canceled out, where the junction is called a colorful boojum. We rigorously prove this in both a macroscopic theory based on the Ginzburg-Landau description in which symmetry and excitations match (including vortex cores), and a microscopic theory in which the Aharonov-Bohm phases of quarks around vortices match.
