QUARK CONFINEMENT STUDY FROM SU(2) LATTICE GAUGE THEORY
Keywords:
Lattice QCD, coulomb gauge, Yang-Mills theoryAbstract
Nowadays, we know that the constituent particles within any nucleon are the bound states of quarkand gluon. The confinement scenarios of this process are still mysterious. However, most physicistsbelieve it can be explained by quantum chromodynamics(QCD) at low energy sector(Infrared). Latticegauge theory is one of the tools to study this low energy QCD by practically doing simulation. Onescenario of confinement is study through Coulomb gauge lattice in which confinement information isknown by studying gluon propagator, ghost form factor and Coulomb potential. Those three objectsare measured by Monte Carlo simulation and implementing Coulomb gauge fixing by relaxationmethod. Now, we get the results of gluon propagator, ghost form factor, and Coulomb potential.
