Aspects of Charmonium

Abstract

Here we discuss three separate topics in charmonium physics. (1) The Omicron \OMC as $1^{--}$ trigluonia, and the charmonium puzzle; the ${\eta }_c^{\prime }(3600)$ search. (2) The decay $\psi {(}^1{P}_1)\to {\pi }^o+J/\psi$ and isospin violating charmonium decays. (3) How to search for ${\chi }_c^{\prime }={\chi }_c(2P)$ charmonium states.
