Abstract
We explore whether “f0(600) or σ" exists as a pole in QCD, by a full lattice QCD simulation on the 83×16 lattice using the plaquette action and Wilson fermions. It is shown that there exists a σ pole, whose mass is as low as that of the ρ, owing to the disconnected diagram of the meson propagator. A discussion is given on the physical content of the σ.
