Photoproduction of baryons with strangeness,such as the Σ(1385),Λ(1520) and possibly the Θ +,are described from measurements at the LEPS/SPring-8 facility in Japan.Linearly polarized photons in the energy rang...

Weigel for his useful program from E-mail exchanges.
For the first time the low-lying J = 1/2 pentaquark states are investigated in the pseudoscalar-vector Skyrme model. Once the conventional baryon properties are fit, other states are predicted without any more adjusta...
