Using QCDLAB2 to Define Lattice Parameter

Lattice Quantum Chromodynamics (LQCD) may be studied in low-energy regimes where non-perturbative approaches are useful because of their computational methods. Determining the lattice parameter, sometimes referred to as the lattice scale or lattice parameter, is a crucial objective in LQCD computations. The best way to get this parameter is to examine the quark-antiquark potential's behavior, which in LQCD simulations may be obtained by first computing the Wilson loops. We used an improved version of QCDLAB 2.0, a program specifically designed for lattice QCD simulations, in this paper. We concentrated on computing planar Wilson loops to extract the interquark potential. SU (3) gauge field configurations were used as the background field in the simulations. In contrast to the earlier work, we present it for larger lattice volumes of 16^4, 32^4, 48^4, and 64^4 in this publication. These simulations are configured with four distinct values of the coupling constant, which correspond to different background field configurations. One-hundred-gauge field configurations that were statistically independent were created and examined for every example. To derive the lattice scale for different lattice volumes, we used Python. It is feasible to translate physical values measured in lattice units into ordinary physical units once the lattice scale is defined. In our previous study, we used the FermiQCD program. With Artan Borici's help, we then switched to the more effective and user-friendly QCDLAB version 2.0, which greatly increased the efficacy of our simulations. In this study, we introduce an upgraded version of QCDLAB2 that uses Python to compute, even for dense lattices.
