Resolving a Mystery in QCD with High Energy Photons

Almost immediately after QCD was recognized as the correct theory of the strong force, it was realized that in addition to the stable nuclear particles (known hadrons) that had already been seen, other entire families of unstable nuclear particles should also exist, which decay into the known hadrons. These new particles, collectively known as "exotic hadrons", include glueballs, hybrids, tetraquarks, and pentaquarks. Experimental searches for exotics for the past 40 years have mostly turned up empty, until recently. I will describe recent results from the LHC that give convincing evidence of tetraquarks, and a new experiment recently begun at Jefferson Lab to search for hybrids.
