Stochastic Confinement and Dimensional Reduction. 1. Four Dimensional SU(2) Lattice Gauge Theory

摘要

By Monte Carlo calculations on a 16 exp 4 lattice the authors investigate four dimensional SU(2) lattice guage theory with respect to the conjecture that at large distances this theory reduces approximately to two dimensional SU(2) lattice gauge theory. Good numerical evidence is found for this conjecture. As a by-product the SU(2) string tension is also measured and good agreement is found with scaling. The adjoint string tension is also found to have a reasonable scaling behaviour. (Atomindex citation 15:042410)
