Observation of Transverse Polarization and Determination of Psionic Form Factors of the $Λ$ Hyperon at $s = 3.773$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a data sample of $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 20.3 fb $^{- 1}$ collected by the BESIII detector at the BEPCII collider, we present a…

Precision measurement of the branching fraction for the decay $ψ (2 S) \to τ^{+} τ^{-}$

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

Using $(2259.3 \pm 11.1) \times 1 0^{6}$ $ψ (2 S)$ events acquired with the BESIII detector, the branching fraction of $ψ (2 S) \to τ^{+} τ^{-}$ is measured with improved precision t…

Search for lepton number violating decays of $D_{s}^{+} \to h^{-} h^{0} e^{+} e^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

Based on 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector operating at the BEPCII collider at center-of-mass energies from 4.128 to 4.226 GeV, a search fo…
