Description
We study the determination of the parity of the pentaquark baryons in two different processes. First, we investigate the Θ+ production via the p->p->->Σ+Θ+ reaction process which was proposed to determine unambiguously the parity of the Θ+. We observe clear differences in the total cross sections and the spin observable Axx. As for the Ξ5 in the K-bar N->KΞ5 one hundred times larger than that for the negative parity one due to a huge destructive interference
