Ya. Azimov (PNPI), K. Goeke (Ruhr-Univ.), I. Strakovsky (GWU)

TL;DR
This paper proposes a mechanism for the production of exotic hadrons, explaining experimental discrepancies, and suggests new experiments to confirm their existence and gather more information about hadrons.
Contribution
It introduces a new hypothesis that exotic hadron production is a distinct hard process, providing a qualitative explanation for experimental observations.
Findings
Exotic hadron production may be a new type of hard process.
The hypothesis explains why certain experiments observe exotics while others do not.
Proposes new experimental approaches to detect and study exotics.
Abstract
On the basis of existing data, we suggest such a mechanism of production for exotic hadrons that can explain, at least qualitatively, why the Theta+-baryon is seen in some experiments and not in others. With our hypothesis, production of exotic hadrons is a new kind of hard processes. We also can propose new experiments to check (and confirm?) existence of exotics and to provide new important information about both exotic and conventional hadrons [The talk is based on the papers by Ya. Azimov, K. Goeke, and I. Strakovsky, Phys Rev D 76, 074013 (2007)]
