Exotic charmonium spectroscopy with CMS

Abstract

The latest results of CMS in the area of exotic quarkonium decays will be presented: observation of a peaking structure in $J/\psi \Phi$ mass spectrum in the decay $B^{\pm }\to J/\psi \Phi K^{\pm }$, search for new bottomonium states in ${\rm Y}(1\mathrm{S}){\pi }^{+}{\pi }^{-}$ mass spectrum, measurement of prompt $J/\psi$ pair production.
