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-…

A model-independent measurement of the CKM angle $γ$ in the decays $B^{\pm} \to [K^{+} K^{-} π^{+} π^{-}]_{D} h^{\pm}$ and $B^{\pm} \to [π^{+} π^{-} π^{+} π^{-}]_{D} h^{\pm}$ ( $h = K, π$ )

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1164

A model-independent determination of the CKM angle $γ$ is presented, using the $B^{\pm} \to [K^{+} K^{-} π^{+} π^{-}]_{D} h^{\pm}$ and $B^{\pm} \to [π^{+} π^{-} π^{+} π^{-}]_{D} h^{\pm}$ decays, with $h = K, π$ . This meas…

Measurement of the Z-boson mass

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1129

The first dedicated $Z$ -boson mass measurement at the LHC with $Z \to μ^{+} μ^{-}$ decays is reported. The dataset uses proton-proton collisions at a centre-of-mass energy of $13$ TeV,…
