    Under the quenched approximation, we perform a lattice calculation for the mass of the ground 4++4^{++} glueball state in E++E^{++} channel on a D=3+1D=3+1 lattice. Our calculation shows that the mass of this state is MG(4++)=3.65(6)(18)GeVM_G(4^{++})=3.65(6)(18)GeV, which rules out the 4++4^{++} or mainly 4++4^{++} glueball interpretation for ξ(2230)\xi(2230).Comment: 10 pages and 1 figur
