Measurement of $f_{s} / f_{u}$ variation with proton-proton collision energy and $B$ -meson kinematics

LHCb collaboration, R. Aaij, C. Abellán Beteta +903

The ratio of the $B_{s}^{0}$ and $B^{+}$ fragmentation fractions $f_{s}$ and $f_{u}$ is studied with $B_{s}^{0} \to J / ψ ϕ$ and $B^+\to\mathrm{J…

Measurement of the cross section for $e^{+} e^{-} \to Ξ^{-} Ξ ˉ^{+}$ and observation of an excited $Ξ$ baryon

BESIII Collaboration, M. Ablikim, M. N. Achasov +483

Using a total of 11.0 fb $^{- 1}$ of $e^{+} e^{-}$ collision data with center-of-mass energies between 4.009 GeV and 4.6 GeV and collected with the BESIII detector at BEPCII, we measu…

Observation of the leptonic decay $D^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +479

We report the first observation of $D^{+} \to τ^{+} ν_{τ}$ with a significance of $5.1 σ$ . We measure ${\cal B}(D^+\toτ^+ν_τ) = (1.20\pm0.24_{\text{stat.}}\pm0.12_{\text{syst.}})\times10^{-3…

Precision measurement of the branching fractions of $η^{'}$ decays

M. Ablikim, M. N. Achasov, S. Ahmed +460

Based on a sample of $(1310.6 \pm 7.0) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we present measurements of $J / ψ$ and $η^{'}$ absolute branching fractions usin…

Measurement of the branching fraction of $J / ψ \to ω η^{'} π^{+} π^{-}$ and search for $J / ψ \to ω X (1835), X (1835) \to η^{'} π^{+} π^{-}$ decay

BESIII Collaboration

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected by the BESIII detector at BEPCII during 2009 and 2012, we study the $J / ψ \to ω η^{'} π^{+} π^{-}$ hadronic process.…

Measurement of b-hadron fractions in 13 TeV pp collisions

LHCb Collaboration, R. Aaij, C. Abellán Beteta +843

The production fractions of $B_{s}^{0}$ and $Λ_{b}^{0}$ hadrons, normalized to the sum of $B^{-}$ and $B^{0}$ fractions, are measured in 13 TeV pp collisions using data c…
