摘要
Angular distributions for production of the Theta(+) pentaquark are calculated for the collisions of polarized protons with polarized target protons. We compare calculations based on different assumptions concerning spin and parity (J=1/2(+/-),3/2(+/-)) of the Theta(+) state. For a wide class of interactions the spin correlation parameters describing the asymmetric angular distributions are calculated up to 250 MeV above production threshold. The deviations from the near-threshold behavior are investigated.
