Lattice asymmetry in finite temperature gluodynamics
- Bogolyubov Institute for Theoretical Physics, National Academy of Sciences of Ukraine, Kiev 143 (Ukraine)
The role of the lattice asymmetry parameter {xi} in the phase structure description of SU(2) and SU(3) gluodynamics at finite temperature in the SU(N){approx_equal}Z(N) approach has been studied analytically. The properties of thermodynamic quantities have been investigated near the physical border. The effective action which includes the first nontrivial order from the spacelike part allows estimates to be made of the phase structure not only close to the physical border but in the whole area of couplings. We find that thermodynamic quantities depend on {xi} and this dependence may be strong enough, up to discontinuity over this parameter for some of them. {copyright} {ital 1997} {ital The American Physical Society}
