# Properties of the twisted Polyakov loop coupling and the infrared fixed point in the SU(3) gauge theories

@article{Itou2013PropertiesOT, title={Properties of the twisted Polyakov loop coupling and the infrared fixed point in the SU(3) gauge theories}, author={Etsuko Itou}, journal={Progress of Theoretical and Experimental Physics}, year={2013}, volume={2013} }

We report the nonperturbative behavior of the twisted Polyakov loop (TPL) coupling constant for the SU(3) gauge theories defined by the ratio of Polyakov loop correlators in finite volume with twisted boundary condition. We reveal the vacuum structures and the phase structure for the lattice gauge theory with the twisted boundary condition. Carrying out the numerical simulations, we determine the nonperturbative running coupling constant in this renormalization scheme for the quenched QCD and N…
