Radiative φ→f0(980)γ decay in light cone QCD sum rules

The light cone QCD sum rules method is used to calculate the transition form factor for the radiative φ→f0γ decay, assuming that the quark content of the f0 meson is pure s̄s state. The branching ratio is estimated to be B(φ→f0γ)=3.5×(1±0.3)×10−4. A comparison of our prediction on branching ratio with the theoretical results and experimental data existing in literature is presented.
