dc.descriptionWe explore whether "f$_{0}$(600) or $σ$" exists as a pole in QCD, by a full lattice QCD simulation on the $8^{3} \times 16$ lattice using the plaquette action and Wilson fermions. It is shown that a low-mass $σ$ pole exists owing to the disconnected diagram of the meson propagator. A discussion is given on the physical content of the $σ$.
