High Energy Behaviour of Light Meson Photoproduction

TL;DR

This paper analyzes recent experimental data on light meson photoproduction at high energies, comparing it with theoretical predictions based on quark counting rules to understand the underlying particle interaction mechanisms.

Contribution

It provides a detailed comparison of experimental measurements with quark counting rule predictions in the high-energy regime for meson photoproduction.

Findings

Experimental data generally agree with quark counting rule predictions at high energies.

Discrepancies observed at certain energy points suggest possible refinements in theoretical models.

Results support the applicability of quark counting rules in describing high-energy meson photoproduction.

Abstract

We evaluated recent CLAS Collaboration measurements for the $90^\circ$ meson photoproduction off the nucleon using a tagged photon beam spanning the energy interval $s = 3 - 11$ GeV$^2$. The results are compared with the "Quark Counting Rules" predictions.
