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

Simon Hands, Seyong Kim, Jon-Ivar Skullerud

The heavy quarkonium spectrum of Two Color QCD (QC$_2$D) at non-zero quark
chemical potential $\mu$ and temperature $T$ with $\mu/T\gg1$ 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.
