Abstract
We investigate the photoproduction of Θ+ from the proton and neutron, γN→K¯Θ+. Assuming that spin and parity of Θ+ 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 Θ+ via the reaction γp→K¯0Θ+.
