QCD exotics and where to find them
→
Europe/London
Description
QCD predicts a zoo of "exo3c" hadrons with more complex internal structures than the quark- antiquark mesons and three-quark baryons of the original quark model. Nowadays, there are experimentally observed states that are often assigned to the light meson or charmonium sector, indicating an exo3c nature. Such exotic particles include glueballs, hybrids, and tetraquarks. Not only do these states pose a theoretical challenge, but experimentally it is often difficult to distinguish and characterize exotic and non-exotic matter. The talk will discuss recent experimental results and techniques for identifying and characterizing exotic QCD states. In addition, the talk will provide an overview of the individual advantages of different production processes in accessing exotic matter.
