Helicity amplitude analysis of χ cJ → ϕϕ

Helicity amplitude analysis of χ cJ → ϕϕ

Using (447.9 ± 2.3) million ψ(3686) events collected with the BESIII detector, the decays of χcJ→ ϕϕ (J = 0, 1, 2) have been studied via the decay ψ(3686) → γχcJ. The branching fractions of the decays χcJ→ ϕϕ (J = 0, 1, 2) are determined to be (8.59 ± 0.27 ± 0.20) × 10−4, (4.26 ± 0.13 ± 0.15) × 10−4...
