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

We show that the cross sections of the ${\mathrm{\Theta }}^{+}$-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 ${\mathrm{\Theta }}^{+}$-pentaquark.
