We study the scaling behaviour of lattice quantum chromodynamics by comparing the β dependence of the string tension and the 0++ glueball mass.

Abstract

We study the scaling behaviour of lattice quantum chromodynamics by comparing the β dependence of the string tension and the 0++ glueball mass. We use a source method at β=5.7, β=5.9 and β=6.1, on lattices from 93· 24 to 163· 32. Assuming a string tension of about (420 MeV)2, the lattice spacing ranges from 0.16 to 0.08 fm. In order to separate finite volume from scaling violation effects we have compared data from lattices having approximately the same overall physical size at the different values of β. We find deviations from scaling to be very small. © 1988.
