Confinemet-Deconfinement Phase Transition on SU(2) Pure Gauge Theory at Finite Temperature

Nowo Riveli

In this thesis we are investigating the mechanism of quark connement by means of pure lattice gauge theory. In particular, we conduct the simulation in pure SU(2) gauge system, where its non-Abelian properties believed to give a representative insight of the connement mechanism. We studied the behaviour of quark free energy as a function of temperature, and expecting a critical temperature where connement state will turn into deconnement state. Thus the free energy is taken to be the order parameter for connement-deconnement phase transition. At the beginning we give a short review of lattice gauge eld theory, and of the numerical algorithms needed for our Monte Carlo simulations. Afterwards we introduce Polyakov loop as the lattice observable where we can extract the physical free energy. Hence, we are using Polyakov loop as the order parameter on the lattice to investigate the phase transition. Before running the simulation, we give the explanation on constructing a
nite temperature physics on the lattice. At the end, we present the result of our Monte Carlo result, which give the conclusion that for pure SU(2) gauge theory, there exist a critical nite temperature where deconnement occur.
