Theoretical predictions for exotic hadrons

摘要

In this contribution the authors discuss current theoretical expectations for the properties of light meson exotica, which are meson resonances outside the q(anti q) quark model. Specifically they discuss expectations for gluonic hadrons (glueballs and hybrids) and multiquark systems (molecules). Experimental candidates for these states are summarized, and the relevance of a TCF to these studies is stressed.
