Comment on the ${\Theta }^{+}$-production at high energy

Abstract

We show that the cross sections of the ${\Theta }^{+}$-pentaquark production in different processes decrease with energy faster than the cross sections of production of the conventional three-quark hyperons. Therefore, the threshold region with the initial energy of a few GeV or less seemsto be more favorable for the production and experimental study of ${\Theta }^{+}$-pentaquark.
