| contents | The CMS Collaboration has performed many studies in the field of heavy flavor spectroscopy. In this report, recent studies on exotic resonances in proton-proton collisions at $\sqrt{s} = 13$ TeV at CMS are presented. For the exotic hadrons, these results include the first evidence for X(3872) in heavy-ion collisions and three new structures in $J/ψJ/ψ$ mass spectrum. Beside the exotic hadrons, we also found new decay channels in conventional beauty hadrons, including $B^{0}_{s}\rightarrowψ(2S)K^{0}_{S}$, $Λ_{b}^{0}\rightarrow J/ψΞ^{-}K^{+} $, $B^{0} \rightarrow ψ(2S)K^{0}_{S}π^{+} π^{-}$, and $Ξ_{b}^{-} \rightarrow ψ(2S)Ξ^{-}$. |
