Study on Quark Confinement Lattice QCD Calculations Using Simulation Techniques

To observe the phenomenon of quark confinement it is needed to investigate whether the linear term in QCD potential actually exists. For this purpose perturbative techniques were insufficient. But numerical simulations of lattice gauge theory on a space time lattice is an important tool for lattice QCD calculations. In this paper we review the Wilson loop techniques for the study of quark confinement using the gauge invariance.
