Measurement of the double Dalitz decay $η \to e^{+} e^{-} e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detector, we study the rare double Dalitz decay of $η \to e^{+} e^{-} e^{+} e^{-}$ …

Amplitude Analysis of the Isospin-Violating Decay $J / ψ \to γ η π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we perform the first amplitude analysis of the process $J / ψ \to γ η π^{0}$ . The decay is dominated b…

Observation of $Λ_{c}^{+} \to n π^{+} η$ and search for $Λ_{c}^{+} \to n a_{0} (980)^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +719

By analysing 6.1 $fb^{- 1}$ of data collected at center-of-mass energies between $s = 4.600$ and 4.843 $GeV$ with the BESIII detector at the BEPCII collider, we obser…

Search for the rare decay $J / ψ \to γ D^{0} + c . c .$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $(10087 \pm 44) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we search for the rare decay $J / ψ \to γ D^{0} + c . c .$ for the first time. No obvious signal is observed and t…

Measurements of the branching fractions of the $P$ -wave charmonium spin-singlet state $h_{c} (^{1} P_{1}) \to h^{+} h^{-} π^{0} / η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +649

Based on $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events, we investigate four hadronic decay modes of the $P$ -wave charmonium spin-singlet state $h_{c} (^{1} P_{1}) \to h^{+} h^{-} π^{0} / η$ ($h=…
