ESTIMATE FOR THE 0⁺⁺ GLUEBALL MASS IN QCD

Abstract

We obtain accurate result for the lightest glueball mass of QCD in three dimensions from lattice Hamiltonian field theory. Using the dimensional reduction argument, we suggest that a good approximation for confining theories in the 0 ++ glueball mass in (3+1)-dimensional QCD is about 1.71 GeV.
