"The Ongoing Quest to Understand the QCD Spectrum of Mesons"

Dr. Matthew Shepherd
Indiana University


For many decades the conventional quark anti-quark picture of mesons has provided a satisfactory description of the experimentally observed spectrum of mesons.  In recent years, strong experimental evidence of meson states that cannot be formed by a quark anti-quark pair has emerged.  At the same time, recent first-principles calculations of the meson spectrum from quantum chromodynamics (QCD) have suggested the presence of unconventional meson states.  However, the correspondence between newly-discovered unconventional states and predicted states is not immediately apparent.  In this talk I'll motivate using meson spectroscopy as a tool for studying QCD, discuss a selection of recent experimental results, and future prospects for studying the meson spectrum.
