First measurements of the absolute branching fraction of $Λ_{c} (2625)^{+} \to Λ_{c}^{+} π^{+} π^{-}$ and upper limit on $Λ_{c} (2595)^{+} \to Λ_{c}^{+} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +613

The absolute branching fraction of the decay $Λ_{c} (2625)^{+} \to Λ_{c}^{+} π^{+} π^{-}$ is measured for the first time to be $(50.7 \pm 5. 0_{stat.} \pm 4. 9_{syst.}) %$ with 36…

First observation of the decay $Λ_{c}^{+} \to n K_{S}^{0} π^{+} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +636

Based on 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated at center-of-mass energies between $4599.53$ MeV and $4698.82$ MeV with the BESIII detector, the decay $Λ_{c}^{+}\…

Observation of $χ_{c J} \to 3 (K^{+} K^{-})$

BESIII Collaboration, M. Ablikim, M. N. Achasov +642

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay processes $χ_{c J} \to 3 (K^{+} K^{-})$ ( $J = 0, 1, 2$ )…

Improved measurement of the branching fractions for $J / ψ \to γ π^{0}$ , $γ η$ and $γ η^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +609

Using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detector, the decays of $J / ψ \to γ π^{0} (η, η^{'}) \to γ γ γ$ are studied. Newly measu…
