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…

Search for the lepton number violating process $Ξ^{-} \to Σ^{+} e^{-} e^{-} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +691

We present a search for the lepton number violating decay $Ξ^{-} \to Σ^{+} e^{-} e^{-} + c . c .$ with $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected by the BESIII detector at the BEPCII…

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…

Study of the Magnetic Dipole Transition of $J / ψ \to γ η_{c}$ via $η_{c} \to p p ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +692

Using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the $e^{+} e^{-}$ BEPCII collider, we present the first amplitude analysis of $J / ψ \to γ p p ˉ$ wit…

Based on a sample of $(10.087 \pm 0.044) \times 1 0^{9} J / ψ$ events collected by the BESIII detector at the BEPCII collider, we perform the first search for the lepton number violati…
