Lattice study of static quark-antiquark interactions in dense quark matter

Understand

In this paper we study the interactions among a static quark-antiquark pair in the presence of dense two-color quark matter with lattice simulation.

• To this end we compute Polyakov line correlation functions and determine the renormalized color averaged, color singlet and color triplet grand potentials.
• The color singlet grand potential allows us to elucidate the number of quarks induced by a static quark antiquark source, as well as the internal energy of such a pair in dense quark matter.
• We furthermore determine the screening length, which in the confinement phase is synonymous with the string breaking distance.
