Abstract

We present a search for the possible I(JP)=0(2+)I(J^{P})=0(2^{+}) tetraquark state with sssˉsˉss{\bar s}{\bar s} quark content in quenched improved anisotropic lattice QCD. Using various local and non-local interpolating fields we determine the energies of ground-state and second ground state using variational method. The state is found to be consistent with two-particle scattering state, which is checked to exhibit the expected volume dependence of the spectral weights. In the physical limit, we obtain for the ground state, a mass of 2123(33)(58)2123(33)(58) MeV which is higher than the mass of experimentally observed f(2010)f(2010). The lattice resonance signal obtained in the physical region does not support a localized JP=2+J^{P} =2^{+} tetraquark state in the pion mass region of 300800300 - 800 MeV. We conclude that the 4q4q system in question appears as a two-particle scattering state in the quark mass region explored here.
