非零重子密度下双色QCD的非相对论谱

Non-relativistic spectrum of two-color QCD at non-zero baryon density

Simon Hands, Seyong Kim, Jon-Ivar Skullerud

摘要:

本文采用非相对论的格点QCD(QC $_2$ D)$_2$ D,在$S$ -和$P$ -两个波道上计算了非零夸克化学势$μ$和温度$T$与$μ/T\gg1$下的双色QCD(QC $_2$ D)的重夸克偶素谱.由于$μ$是变化的,夸克偶素谱显示出三个独立的区域,证实了以前的发现,有三个不同的物理制度的QC $_2$ D在低温和重子密度:强子物质,夸克/夸克物质,和deconfined物质。结果用双色重子介质中重-轻$Qq$态的形成来解释。

英文摘要:

The heavy quarkonium spectrum of Two Color QCD (QC$_2$D) at non-zero quark chemical potential $μ$ and temperature $T$ with $μ/T\gg1$ has been calculated in both $S$- and $P$-wave channels using a lattice non-relativistic formulation of QC$_2$D. As $μ$ is varied, the quarkonium spectra reveal three separate regions, corroborating previous findings that there are three distinct physical regimes of QC$_2$D at low temperature and high baryon density: hadronic matter, quark/quarkyonic matter, and deconfined matter. The results are interpreted in terms of the formation of heavy-light $Qq$ states in the two-color baryonic medium.
