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