| Abstract: |
It has long been suggested that spectrum of bound states of QCD may exhibit states with "valence gluons" as a result of the gluon-gluon interaction in QCD. This expectation has been bolstered by recent lattice QCD calculations of the light meson spectrum, which indicate the presence of states with gluonic degrees of freedom. The GlueX experiment plans to utilize a high intensity photon beam derived from the upgraded 12 GeV electron beam at Jefferson Lab to conduct a precision study of the light meson spectrum in search of hybrid mesons. The motivation, design, and current construction progress of the experiment will be discussed. In addition, the prospects for significantly enhancing the scientific scope GlueX using a particle identification system based on the BaBar DIRC detector will be presented. |
