Photoproductions of K ⁺Λ and K ⁰Λ Studied by Using Isobar Model

We have investigated the neutral kaon photoproduction off a neutron by using an isobar model based on our previous study. The unknown parameters were extracted by fitting the model prediction to experimental data. We analyzed the two Λ channels, i.e., K ⁺Λ and K ⁰Λ channels, simultaneously. We used two different approaches in the fitting process which lead to two different models. We compare the agreement between model prediction and experimental data for both models quantitatively. The result reveals the effect of including the K ⁰Λ data on the model and thus improves our understanding on the kaon photoproduction process.
