Exotic meson studies at CMS



Primary authors

Abstract content

CMS has accumulated large amount of dimuon events at 7 and 8 TeV center-mass-energy. Fruitful results have been produced using these datasets. This talk will cover the observation of two structures in jpsi+phi mass spectrum via exclusive B+-> jpsi phi K+ decays, while the first one confirms a previous observation from CDF experiment, and the second one has been observed for the first time. A related decay channel B+-> psi2s phi K+ has been observed by CMS for the first time and will be reported.
