Abstract

We derive the separate helicity amplitudes involving the partial wave analysis in the process of pseudo-scalar meson photon productions with J^P=3/2⁺, which is independent on model. According to parity, the general amplitude in the case of J^P=1/2^- is given out. We prove this general amplitude is corresponding to the situation of λ=-1 as adopting the circular polarization. Finally, the formulas of scattering amplitudes involving the photon-meson production with J^P=3/2⁺ are obtained from the chiral quark model.
