      Ablikim, M.; Achasov, M. N.; Ai, X. C.; Albayrak, O.; Albrecht, M.; Ambrose, D. J.; Amoroso, A.; Lou, Xinchou; BESIII Collaboration (Amer Physical Soc, 2014-11-03)
      Using 1.06 x 10⁸ ψ(3686) events recorded in e⁺e⁻ collisions at √s = 3.686 GeV with the BESIII at the BEPCII collider, we present searches for C-parity violation in J/ψ → γγ and γϕ decays via ψ(3686) → J/ψ π⁺π⁻. No significant ...
