Determination of the parity of the pentaquark baryons : Theta+ and Xi5
Seung-Il Nam, Atsushi Hosaka, Hyun-Chul Kim
Abstract
We study determination of the parity of the pentaquark baryons in two different processes. First, we investigate the Theta+ production via the vecp vecp -> Sigma+ Theta+ reaction process which was proposed to determine unambiguously the parity of Theta+. We observe the clear differences in the total cross sections and the spin observable Axx. As for the Xi5 in the barK N -> K Xi5 reaction process, the total cross section for the positive parity presents about one hundred times lager than that of the negative one due to the huge destructive interference.
