Description
Quantum Chromodynamics (QCD) provides a theoretical framework for understanding interactions among quarks and gluons within hadrons. However, the influence of gluonic excitations on hadron characteristics and structure remains uncertain. Recent discoveries of potentially ex- otic hadrons underscore the need for precise spectroscopic measurements to decipher the strong force. This discussion focuses on ongoing analy- ses using photoproduction data from the GlueX experiment at Jefferson Lab, with emphasis on η(′)π systems. Specifically, we explore the produc- tion mechanisms of the a2(1320) mesons in these channels, a step toward unveiling exotic quantum-number hybrid mesons. Furthermore, the dis- cussion will cover the application of an amplitude analysis utilizing the polarized photon beam of the GlueX experiment, to identify the lightest hybrid mesons.
