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

TL;DR

This paper proposes a novel production mechanism for the hypothesized pentaquark state involving exotic Regge trajectory exchange, predicting distinctive momentum distribution patterns compared to ordinary hyperons.

Contribution

It introduces a new production mechanism for the $ heta^+$ pentaquark based on exotic Regge trajectories in the $t$ channel, highlighting potential differences in momentum distributions.

Findings

Momentum distributions of $ heta^+$ differ from ordinary hyperons.

The mechanism suggests a new pathway for pentaquark production.

Exotic Regge trajectories play a key role in the proposed process.

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.
