Search for Exotic Mesons at CMS

Exotic meson spectroscopy searches at the LHC yielded interesting results. Using an integrated luminosity of 25.6 inverse femtobarn recorded in proton-proton collisions at 7 TeV and 8 TeV, CMS searched enhancements in multi-lepton final states in the mass range below the Y(1S)Y(1S) mass. Results will be presented and discussed.
