Description

Lattice Quantum Chromo-dynamics (LQCD) is an algorithmic formulation of QCD, the mathematical model that describes quarks and their interactions. Computations in LQCD are typically very expensive and run on dedicated supercomputers and large computer clusters for many months. In this paper the calculations are performed in one of the clusters for supercomputing of HP-SEE (High-Performance Computing Infrastructure for South East Europe’s Research Communities) project, that is located in Bulgaria (BG HPC). We use parallel computing with Fermiqcd software, to determine the static quark-antiquark potential. In LQCD the static quark-antiquark potential can be derive from the Wilson loops. The standard method use rectangular Wilson loops, while we test 3-D Wilson loops, using simulation with SU(3) gauge field configuration for different values of coupling constant and for different lattice sizes. The calculations are made for 100 configurations, statistically independent, of gauge fields of the lattice. We extrapolate in continuum limit for different lattice constant to take string tension parameter and to compare with the experimental value.
