Coupled-Channel Partial Wave Analysis of J/ψ → φ π+ π− and J/ψ → φ K+ K− — •Markus Kuhlmann for the BESIII collaboration — Institut für Experimentalphysik I, Ruhr-Universität Bochum
Gluonic bound states like glueballs or hybrids and multiquark states are predicted by QCD. Hadronic decays of charmonia are gluon rich processes, where the production of those exotics is expected. In this talk, preliminary results of the analysis of the decays J/ψ → φ π+ π− and J/ψ → φ K+ K− are presented, using the worlds largest data sample of about 1.3 · 109 J/ψ events, collected with the Beijing Spectrometer III (BESIII) in positron-electron annihilations at the Beijing Electron-Positron Collider (BEPCII). The data selection, background analysis, and preliminary results of a coupled-channel partial wave analysis will be discussed.
