有限密度封闭介质中的全息强子

Holographic Hadrons in a Confining Finite Density Medium

Yunseok Seo, Jonathan P. Shock, Sang-Jin Sin, Dimitrios Zoakos

摘要:

我们研究了有限重子密度下强子谱的一个扇区。我们使用一个非超对称的重力对偶的封闭规范理论,它表现出一个运行的量子。介子与有限密度介质的相互作用在对偶理论中被编码为味D 7-膜和由包裹的D5-膜提供的重子顶点之间的力平衡。当当前夸克质量m_q足够大时,介子质量减小,随着重子密度的增加呈现出有趣的谱流,而当m_q很小时,谱流表现出更为复杂的行为。

英文摘要:

We study a sector of the hadron spectrum in the presence of finite baryon density. We use a non-supersymmetric gravity dual to a confining guage theory which exhibits a running dilaton. The interaction of mesons with the finite density medium is encoded in the dual theory by a force balancing between flavor D7-branes and a baryon vertex provided by a wrapped D5-brane. When the current quark mass m_q is sufficiently large, the meson mass reduces, exhibiting an interesting spectral flow as we increase the baryon density while it has a more complicated behaviour for very small m_q.
