Under the quenched approximation, we perform a lattice calculation for the mass of the ground 4++ glueball state in E++ channel on a D =3 + 1 lattice. Our calculation shows that the mass of this state is MG (4+ +) = 3.65(6)(18) GeV, which rules out the 4++ or mainly 4++ glueball state interpretation for ξ(2230).
