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-…

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 hidden-charm tetraquark with strangeness in $e^{+} e^{-} \to K^{+} D_{s}^{-} D^{ 0} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +571

We report a search for a heavier partner of the recently observed $Z_{cs} (3985)^{-}$ state, denoted as $Z_{cs}^{' -}$ , in the process $e^{+} e^{-}\rightarrow K^{+}D_{s}^{*-}D^…

Observation of the $Y (4230)$ and a new structure in $e^{+} e^{-} \to K^{+} K^{-} J / ψ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +560

The cross sections of $e^{+} e^{-} \to K^{+} K^{-} J / ψ$ at center-of-mass energies from 4.127 to 4.600~GeV are measured based on 15.6 fb $^{- 1}$ data collected with the BESIII detector…

Measurement of integrated luminosities at BESIII for data samples at center-of-mass energies between 4.0 and 4.6 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +550

The integrated luminosities of the data samples collected in the BESIII experiment in 2016--2017 at center-of-mass energies between 4.19 and 4.28 GeV are measured with a precision…

Number of $J/ ψ$ events at BESIII

BESIII Collaboration

Using inclusive decays of the $J/ ψ$ , a precise determination of the number of $J/ ψ$ events collected with the BESIII detector is performed. For the two data sets taken in 2…
