Accessing glue through photoproduction measurements at GlueX

TL;DR

The GlueX experiment at Jefferson Lab uses photoproduction with polarized photons to explore the spectrum of hadronic states, especially hybrid mesons with gluonic components, providing new experimental insights.

Contribution

This work reports initial results from GlueX's data collection, demonstrating its capability to study gluonic contributions to hadron spectra and search for hybrid mesons.

Findings

First results from GlueX data taking in 2018.

Evidence supporting the experiment's ability to identify hybrid mesons.

Enhanced understanding of gluonic contributions to hadron structure.

Abstract

Photoproduction experiments are a key tool in the investigation of the spectrum of hadronic states and the way gluons contribute to this spectrum. The GlueX experiment, located at Jefferson Lab, features a linearly polarized tagged photon beam and its detector system is optimized to measure a wide range of neutral and charged final states. GlueX offers unique capabilities to study the spectrum of hadrons and is dedicated to the search for hybrid mesons, states with gluonic degrees of freedom. This talk presents first results from our initial campaign of data taking which finished in 2018.
