I analyze a possibility of building an isobar model of the kaon–hyperon pair photoproduction in the γp → K ⁺Λ, , and γp → K ⁺Σ processes, where the Born terms play a comparatively small role in the full amplitude. The total width of hadron resonances can be written in the form of a sum of partial contributions into the K ⁺Λ, , and K ⁺Σ channels, and the effective inelastic channel with zero strangeness. The introduction of the effective inelastic channel makes it possible to partially restore the broken unitarity of the total amplitude of photoproduction. The latter includes the gauge-invariant Born and resonant s-, t-, and u-channel contributions calculated in the tree-level approximation. The obtained sets of hadron decay widths of intermediate resonances and coupling constants calculated using these decay widths allow one to equally well reproduce the total and some differential cross sections of the K ⁺Λ, , and K ⁺Σ photoproduction.

我分析了在γp → K ⁺ Λ ，和γp → K ⁺ Σ过程中建立kaon - hyperon对光产生的等压线模型的可能性，其中Born项在整个振幅中起相对较小的作用。强子共振的总宽度可以写成K ⁺ Λ ，和K ⁺的部分贡献之和的形式Σ通道，以及零陌生度的有效非弹性通道。有效的非弹性通道的引入使得可以部分恢复光产生的总振幅的破碎的统一性。后者包括在树级近似中计算的规范不变的Born和共振s-，t-和u通道贡献。所获得的一组中间共振的强子衰减宽度和使用这些衰减宽度计算出的耦合常数，使人们能够同样好地再现K ⁺ Λ和K ⁺ Σ光产生的总截面和某些差分截面。
