Abstract

It is shown in SU(2) gauge theory with two degenerate flavours and an 8 4 lattice that under the alternative assumptions of flavour independence of Λ MS , or that (〈 ψψ〉 N F =0 /〈 ψψ〉 N F =2 ) 1 3 m=0 behaves like the ratio of the corresponding spacing the glueball mass ratio, r= m N F=2 g / m N F=0 g , is 1.86 +0.40 −0.31.
