| 英文摘要 | The Q(2) dependencies of Roper resonance (N*(1440)) helicity amplitudes have been discussed based on two assumptions: (i) the Roper resonance is an excitation of one of the three quarks, and (ii) the quarks are surrounded by a pion-meson cloud. Our study shows that the mixing of the ground state in the Roper wavefunction caused by the pion meson cloud together with the pion meson cloud itself is crucial for the predictions of the photoproduction amplitudes of the Roper resonance. It is found that our model can give a good description for the helicity amplitudes of the Roper resonance comparing with the experimental measurement. |
