On a Possible Mechanism of the Production of Pentaquark States $\Theta (ud\bar{s}ud)$

Abstract

A new mechanism of the production of hypothetical $\Theta (ud\bar{s}ud{)}^{+}$ pentaquark state is suggested. The considered mechanism is based on the exchange by exotic Regge trajectories in the $t$ channel. It is shown that the momentum distributions of ${\Theta }^{+}$ baryons can differ significantly from the ones of the ordinary hyperons.
