Constraints on the CKM angle $γ$ from $B^{\pm} \to D h^{\pm}$ decays using $D \to h^{\pm} h^{' \mp} π^{0}$ final states

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994

A data sample collected with the LHCb detector corresponding to an integrated luminosity of 9 fb $^{- 1}$ is used to measure eleven $C P$ violation observables in $B^{\pm} \to D h^{\pm}$ de…

Identification of charm jets at LHCb

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994

The identification of charm jets is achieved at LHCb for data collected in 2015-2018 using a method based on the properties of displaced vertices reconstructed and matched with jet…

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…

Observation of $J / ψ$ decays to $e^{+} e^{-} e^{+} e^{-}$ and $e^{+} e^{-} μ^{+} μ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +543

Using a data sample of $4.481 \times 1 0^{8} ψ^{'}$ events collected with the BESIII detector, we report the first observation of the four-lepton-decays $J / ψ \to e^{+} e^{-} e^{+} e^{-}$ and $J…

Search for massive long-lived particles decaying semileptonically at sqrt(s)=13 TeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +996

A search is performed for massive long-lived particles (LLP) decaying semileptonically into a muon and two quarks. Two kinds of LLP production processes were considered. In the fir…

Search for invisible decays of the $Λ$ baryon

BESIII Collaboration, M. Ablikim, M. N. Achasov +498

A search for invisible decays of the $Λ$ baryon is carried out in the process $J / ψ \to Λ Λ ˉ$ based on $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detect…
