The role of vector-baryon channels and resonances in the $\gamma p\to K^0{\Sigma }^{+}$ and $\gamma n\to K^0{\Sigma }^0$ reactions near the $K^{\ast }\Lambda$ threshold

A. Ramos, E. Oset

We have studied the $\gamma p\to K^0{\Sigma }^{+}$ reaction in the energy region around the $K^{\ast }\Lambda$ and $K^{\ast }\Sigma$ thresholds, where the CBELSA/TAPS cross section shows a sudden drop and the differ…
