【报告摘要】

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.

Kai Yi got his PhD in 2004 from Johns Hopkins University. From 2004 to 2008, he worked at SLAC as a posdoc. He obtained a position at University of Iowa in 2008 as an assistant research scientist and became an assistant adjunct professor since 2014 to the present. His research interest focus on the hadron physics in CDF, CMS experiments, such as the study of the vector Y(4140) meson.
