Abstract: | Photoproduction of ${K\Sigma}$ on the nucleon in four isospin channels has been investigated near their production thresholds by means of an isobar model. It is shown that in the proton channels ( ${K^+\Sigma^0}$ and ${K^0\Sigma^+}$ channels) the model can nicely reproduce experimental data. Due to the uncertainties in the neutron helicity amplitudes our predictions imply some uncertainties in the observables of the neutron channels ( ${K^+\Sigma^-}$ and ${K^0\Sigma^0}$ channels). |
