/ Abstract

Abstract Using lattice QCD with dynamical Wilson fermions, we study I = 0 and J P = 0 + channel which is constructed by , in order to search for the σ meson. Our preliminary result shows that the connected and disconnected diagrams contribute to the σ meson propagator in the same order.
