全息QCD中的核物质到奇异物质跃迁

Nuclear matter to strange matter transition in holographic QCD

Youngman Kim, Yunseok Seo, Sang-Jin Sin

摘要:

我们构造了一个简单的全息QCD模型来研究核物质到奇异物质的跃迁。通过对稳定的D4/D 6/D 6组态施加力平衡条件,处理了稠密介质与强子的相互作用。通过考虑中等和轻味膜与沿R^3空间均匀分布的重子顶点的相互作用,并要求能量最小,我们发现存在一个定义良好的跃迁密度作为当前夸克质量的函数。我们还发现,当密度上升到很高时,中间(或重)和轻夸克的数量相等,正如泡利原理所预期的那样。在这个意义上,泡利原理的效果被实现为D-膜的动力学。

英文摘要:

We construct a simple holographic QCD model to study nuclear matter to strange matter transition. The interaction of dense medium and hadrons is taken care of by imposing the force balancing condition for stable D4/D6/D6 configuration. By considering the intermediate and light flavor branes interacting with baryon vertex homogeneously distributed along R^3 space and requesting the energy minimization, we find that there is a well defined transition density as a function of current quark mass. We also find that as density goes up very high, intermediate (or heavy) and light quarks populate equally as expected from the Pauli principle. In this sense, the effect of the Pauli principle is realized as dynamics of D-branes.
