Anomaly in the K^0_S Sigma^+ photoproduction cross section off the proton at the K* threshold

R. Ewald, A. V. Anisovich, B. Bantes +57

The $\gamma +p\to K^0+{\Sigma }^{+}$ photoproduction reaction is investigated in the energy region from threshold to $E_{\gamma }=2250$\,MeV. The differential cross section exhibits increasin…
