MEAN FIELD STUDY AND UNIVERSALITY IN LATTICE GAUGE THEORY

  • We study manton's action and several other actions in lattice gauge theory with naive mean field approximation method and the method proposed by Shahbazyan. Values of β at crossover point are obtained with different kinds of SU(2) actions by using both mean field approximation method and the method proposed by Shahbazyan. While in later case, universality is assumed and the Monte Carlo results of SU(2) Wilson action and the relations between Wilson action and other actions are taken as input. The results of the two methods are compared and the universality assumption are checked.

MEAN FIELD STUDY AND UNIVERSALITY IN LATTICE GAUGE THEORY

    Corresponding author: LI Wen-Zhu,

Abstract: We study manton's action and several other actions in lattice gauge theory with naive mean field approximation method and the method proposed by Shahbazyan. Values of β at crossover point are obtained with different kinds of SU(2) actions by using both mean field approximation method and the method proposed by Shahbazyan. While in later case, universality is assumed and the Monte Carlo results of SU(2) Wilson action and the relations between Wilson action and other actions are taken as input. The results of the two methods are compared and the universality assumption are checked.
