    "abstract": "Angular distributions for production of the $\\Theta^+$ pentaquark are\ncalculated for the collisions of polarized protons with polarized target\nprotons. We compare calculations based on different assumptions concerning spin\nand parity ($J=1/2^\\pm,3/2^\\pm$) of the $\\Theta^+$ state. For a wide class of\ninteractions the spin correlation parameters describing the asymmetric angular\ndistributions are calculated up to 250 MeV above production threshold. The\ndeviations from the near threshold behavior are investigated.",
