[en] A new multipoles model for four isospin channels of KΣ photoproduction is proposed. The back-ground part is constructed from the suitable Feynman diagrams and the resonance part is parameterized by using the Breit-Wigner form. The model can describe nearly 7000 experimental data points and needs a weighting factor in the K0Σ+ channel. A clear spike is observed in the K+Σ- channel at W ≈ 1.7 GeV which originates from the N(1710)P11 resonance. (author)
