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

Abstract

The heavy quarkonium spectrum of Two Color QCD (QC${}_2$D) at non-zero quark chemical potential $\mu$ and temperature $T$ with $\mu /T\gg 1$ has been calculated in both $S$- and $P$-wave channels using a lattice non-relativistic formulation of QC${}_2$D. As $\mu$ 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.
