Determination of U-spin breaking parameters with an amplitude analysis of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +605

We present a study of the resonant structure of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$ , using quantum-correlated $D^{0} D ˉ^{0}$ data produced at $s = 3.773$ GeV. The data sampl…

Search for the weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

The Cabibbo-allowed weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ has been searched for in a sample of $Λ_{c}^{+} Λ ˉ_{c}^{-}$ pairs produced in $e^{+} e^{-}$ annihilations, corresponding to an i…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ cross section in the vicinity of 3.872 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

We report a measurement of the cross section for the process $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ around the $X (3872)$ mass in search for the direct formation of $e^{+} e^{-} \to X (3872)$ through the tw…

Measurement of the branching fraction and decay asymmetry of $Λ \to nγ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +565

The radiative hyperon decay $Λ \to nγ$ is studied using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector operating at BEPCII. The absolute branching fractio…
