Suppression of Theta+(JP=3/2(+,-)) photoproduction from the proton
Abstract
We investigate the photoproduction of Theta+ from the proton and neutron, gamma N -> Kbar Theta+. Assuming that spin and parity of Theta+ are JP = 3/2(+,-), it is shown that the production from the proton is strongly suppressed as compared with that from the neutron. This could provide a possible explanation for the null results of the recent CLAS experiment in finding Theta+ via the reaction gamma p -> Kbar0 Theta+.
