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-…

Search for the decays $X (3872) \to K_{S}^{0} K^{\pm} π^{\mp}$ and $K^{*} (892) K ˉ$ at BESIII

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

Using a 10.9 fb $^{- 1}$ data sample collected by the BESIII detector at center-of-mass energies from 4.16 to 4.34 GeV, we search for the charmless decays $X(3872) \to K_{S}^{0}K^{\p…

Evidence of transverse polarization of $Ξ^{0}$ hyperon in $ψ (3686) \to Ξ^{0} Ξ ˉ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +684

Using $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, we report an evidence of $Ξ^{0}$ transverse polarization with a sign…

Search for a hypothetical gauge boson and dark photons in charmonium transitions

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

We report a direct search for a new gauge boson, $X$ , with a mass of $17 MeV / c^{2}$ , which could explain the anomalous excess of $e^{+} e^{-}$ pairs observed in the $^{8} Be$ n…

Based on the $(2712.4 \pm 14.4) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector, we present a high-precision study of the $π^{+} π^{-}$ mass spectrum in $ψ(3686)\rightar…
