“…To solve the η(1405/1475) puzzle and to pin down their nature, a precise and comprehensive measurement is prerequisite. The BESIII experiment has collected 10.09 × 10 9 J/ψ decays [30], which provides an excellent opportunity to explore the nature of the η(1405/1475). Meanwhile, comparing to other decay modes, J/ψ → γK 0 S K 0 S π 0 is free of background from similar final states with one fewer or more photon, and can provide a much cleaner sample than the corresponding charged channels.…”

“…The systematic uncertainty associated with the kinematic fit is 1.6%, obtained by the track helix parameter correction method [55]. The total number of J/ψ decays is obtained using inclusive hadron events, and the uncertainty is 0.4% [30]. The uncertainties associated with the decay branching fractions of K 0 S → π + π − and π 0 → γγ are quoted from the PDG [12].…”

Using a sample of (10.09 ± 0.04) × 109J/ψ decays collected with the BESIII detector, partial wave analyses of the decay $$ J/\psi \to \gamma {K}_S^0{K}_S^0{\pi}^0 $$ J / ψ → γ K S 0 K S 0 π 0 are performed within the $$ {K}_S^0{K}_S^0{\pi}^0 $$ K S 0 K S 0 π 0 invariant mass region below 1.6 GeV/c2. The covariant tensor amplitude method is used in both mass independent and mass dependent approaches. Both analysis approaches exhibit dominant pseudoscalar and axial vector components, and show good consistency for the other individual components. Furthermore, the mass dependent analysis reveals that the $$ {K}_S^0{K}_S^0{\pi}^0 $$ K S 0 K S 0 π 0 invariant mass spectrum for the pseudoscalar component can be well described with two isoscalar resonant states using relativistic Breit-Wigner model, i.e., the η(1405) with a mass of $$ 1391.7\pm {0.7}_{-0.3}^{+11.3} $$ 1391.7 ± 0.7 − 0.3 + 11.3 MeV/c2 and a width of $$ 60.8\pm {1.2}_{-12.0}^{+5.5} $$ 60.8 ± 1.2 − 12.0 + 5.5 MeV, and the η(1475) with a mass of $$ 1507.6\pm {1.6}_{-32.2}^{+15.5} $$ 1507.6 ± 1.6 − 32.2 + 15.5 MeV/c2 and a width of $$ 115.8\pm {2.4}_{-10.9}^{+14.8} $$ 115.8 ± 2.4 − 10.9 + 14.8 MeV. The first and second uncertainties are statistical and systematic, respectively. Alternate models for the pseudoscalar component are also tested, but the description of the $$ {K}_S^0{K}_S^0{\pi}^0 $$ K S 0 K S 0 π 0 invariant mass spectrum deteriorates significantly.

Using 448.1 × 106ψ(3686) decays collected with the BESIII detector at the BEPCII e+e− storage rings, the branching fractions and angular distributions of the decays χcJ→ Ξ−$$ \overline{\Xi} $$ Ξ ¯ + and Ξ0$$ \overline{\Xi} $$ Ξ ¯ 0 (J = 0, 1, 2) are measured based on a partial-reconstruction technique. The decays χc1→ Ξ0$$ \overline{\Xi} $$ Ξ ¯ 0 and χc2→ Ξ0$$ \overline{\Xi} $$ Ξ ¯ 0 are observed for the first time with statistical significances of 7σ and 15σ, respectively. The results of this analysis are in good agreement with previous measurements and have significantly improved precision.
