Analysis of the radiative decay J/ψ → γ φ ω at BESIII — •Orestis Afedulidis — Ruhr-Universität Bochum, Bochum, Deutschland

Exotic mesons like glueballs and hybrids are predicted to be copiously produced in radiative J/ψ decays. A good reaction to discover such states is the doubly OZI suppressed decay J/ψ → γ ω φ.
This talk covers the analysis of this process, using the worlds largest data sample of ≈ 10¹⁰ J/ψ events collected with the BESIII detector. Preliminary results of the data selection, background studies and a partial wave analysis will be shown.
