Planar Wilson Loops for Deriving Interquark Potential in Lattice QCD

Dafina Xhako, Rudina Zeqirllari, Artan Boriçi


Calculation techniques of Lattice QCD (Quantum Chromodynamics) offer special opportunities for the treatment of nonperturbative effects of strong interaction in physics. In Lattice QCD the static quark-anti-quark potential can be derive from the Wilson loops. In this paper we use planar Wilson loops to determine the static quark-anti-quark potential. Using simulation with SU(3) gauge field configuration we derive quark-anti-quark potential for different values of coupling constant and for different lattice sizes. Calculations are made for 100 configurations, statistically independent, of gauge fields of the lattice. Finally, we extrapolate for different lattice constant to take string tension parameter.

Keywords: lattice constant, interquark potential, string tension, SU(3) gauge theory, Wilson loops.
