La. Averchenkova et al., ROLE OF THE ASYMMETRY PARAMETER IN DESCRIBING THE PHASE-STRUCTURE OF LATTICE GLUODYNAMICS AT FINITE TEMPERATURES, Physics of atomic nuclei, 60(11), 1997, pp. 1884-1891
The role of the lattice asymmetry parameter xi in describing the phase
structure of SU(2) gluodynamics is studied analytically. It is shown
that renormalization-group relations, which make it possible to elimin
ate the dependence of thermodynamic quantities on the lattice asymmetr
y parameter in the ''naive'' limit, give no way to do this in the SU(N
) similar or equal to Z(N) limit without disturbing results obtained i
n the naive limit. To eliminate this dependence, it is necessary to im
pose an additional condition fixing the parameter xi.
