"Discoveries and Potential Discoveries of New Exotic Hadron Particles at Colliders" by Dr. Kai Yi, Fermi National Accelerator Laboratory
Abstract: The discoveries of numerous new bound quark states since 2003 have revitalized interest in the spectroscopy of exotic bound quark and antiquark systems. These structures do not fit easily into the standard quark model. Proposals like four quark (plus one antiquark) states and other hybrid states have been suggested as explanations. Since 2009, several new bound states have been reported by experiments at colliders. The developing story on our understanding of these structures from collider experiments like CDF, LHCb, CMS, D0, BaBar and BES will be discussed, including the motivation for these new exotic hadron states and potential new physics.
