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…

Observation of $Λ ˉ p \to K^{+} π^{+} π^{-} π^{0}$ and $Λ ˉ p \to K^{+} π^{+} π^{-} 2 π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +750

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector at a center-of-mass energy of $s = 3.097$ GeV, the antihyperon-nucleon annihilation processe…

Measurements of the Absolute Branching Fraction of the Semileptonic Decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ and the Axial Charge of the $Ξ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we study the semileptonic decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ for the first time at an electron-…
