Abstract：
The quantum fluctuations of the chiral Meson-Quark Model is formulated and the mesonhedgehog baryon scattering phase shift is calculated.It is found that the chiral Meson-Quark Model is stable against small oscillations and the resonance exists.The calculated resonance width is consistent with experimental data,but the resonance energy is only half of the experimental data.
