The heavy quarkonium spectrum of Two Color QCD (QC(2)D) at non-zero quark chemical potential mu and temperature T with mu/T >> 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. (C) 2012 Elsevier B.V. All rights reserved.
