ResumoAbstract It is shown in SU(2) gauge theory with two degenerate flavours and an 84 lattice that under the alternative assumptions of flavour independence of Λ MS , or that (〈 ψ ψ〉 N F =0 /〈 ψ ψ〉 N F =2 ) 1 3 m=0 behaves like the ratio of the corresponding spacing the glueball mass ratio, r=mNF=2g/mNF=0g, is 1.86+0.40−0.31.
