Abstract

Using lattice QCD with dynamical Wilson fermions, we study I=0 and $J^{P}=0^{+}$ channel which is constructed by $\frac{1}{\sqrt{2}}(\bar{u}u+\bar{d}d)|0>$ , in order to search for the $\sigma$ meson. Our preliminary result shows that the connected and disconnected diagrams contribute to the $\sigma$ meson propagator in the same order.
