Observation of a structure at 1.84 GeV/c $^{2}$ in the $3 (π^{+} π^{-})$ mass spectrum in $J / ψ \to γ 3 (π^{+} π^{-})$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +362

With a sample of 225.3 million $J / ψ$ events taken with the BESIII detector, the decay $J / ψ \to γ 3 (π^{+} π^{-})$ is analyzed. A structure at 1.84 GeV/c $^{2}$ is observed in the $3(π…

Measurement of $η^{'} \to π^{+} π^{-} e^{+} e^{-}$ and $η^{'} \to π^{+} π^{-} μ^{+} μ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +361

Based on a sample of 225.3 million J/ψevents accumulated with the BESIII detector at the BEPCII, the decays of η' to pi+pi-l+l- are studied via J/ψto γη'. A clear η' signal is obse…

Evidence for η_{c}(2S) in ψ(3686) \to γK_{S}^{0}K^{\pm}π^{\mp}π^{+}π^{-}

The BESIII Collaboration, M. Ablikim, M. N. Achasov +346

We search for the M1 radiative transition ψ(3686) \to γη_{c}(2S) by reconstructing the exclusive η_{c}(2S) \to K_{S}^{0}K^{\pm}π^{\mp}π^{+}π^{-} decay using 1.06 \times 10^8 ψ(3686…

Partial wave analysis of $J / ψ \to γ η η$

M. Ablikim, M. N. Achasov, O. Albayrak +358

Based on a sample of $2.25 \times 1 0^{8}$ $J / ψ$ events collected with the BESIII detector at BEPCII, a full partial wave analysis on $J / ψ \to γ η η$ was performed using the relativistic…
