Photoproduction of Θ baryon from the neutron
Creators
Description
We study photoproduction reactions for Θ+, which was recently observed as a candidate of an exotic five quark state uudds-bar. We employ effective Lagrangian interactions with a pseudoscalar or pseudovector meson-baryon coupling and investigate two cases of spin and parity of Θ+, JP=1/2+ and 1/2-. We calculate cross sections and discuss possibilities to discriminate one from the other
