Grand Canonical Potential for a Static Quark-Antiquark Pair at finite chemical potential
The grand canonical potential for a static quark-antiquark pair at non-vanishing chemical potential was determined at several temperatures. The dynamical staggered simulations were carried out with 2+1 physical quarks along the Lines of Constant Physiscs (LCP). c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

We present numerical results on the static quark–anti-quark grand canonical potential in full QCD at non-vanishing temperature (T) and quark chemical potential (µ). Non-zero µ-s are reached by means of multi-parameter reweighting. The dynamical staggered simulations were carried out for n f = 2 + 1 flavors with physical quark masses on 4 × 12 3 lattices.
متن کاملSinglet Free Energies of a Static Quark-antiquark Pair
Static free energy of a quark-antiquark pair is a frequently used tool to study non-perturbatively the in-medium modification of inter-quark forces. It is calculated as the difference in the free energy of the system with static quarks and the same system without them, while the temperature remains constant. Due to colour symmetry such quantity contains the singlet and the octet contributions, ...
متن کاملSymanzik Improvement In The Static Quark Potential
A systematic investigation of Symanzik improvement in the gauge field action is performed for the static quark potential in quenched QCD. We consider Symanzik improved gauge field configurations on a 16 × 32 lattice with a relatively coarse lattice spacing of 0.165(2) fm. A matched set of Standard Wilson gauge configurations is prepared at β = 5.74 with the same physical volume and lattice spac...
متن کاملThe static quark potential in full QCD ∗
We report results on the static quark potential in two-flavor full QCD. The calculation is performed for three values of lattice spacing a 3 ×48 lattices respectively, at sea quark masses corresponding to mπ/mρ ≈ 0.8–0.6. An RG-improved gauge action and a tadpole-improved SW clover quark action are employed. We discuss scaling of mρ/ √ σ and effects of dynamical quarks on the potential.
