Measurement of the branching fraction of $D_{s}^{+} \to ℓ^{+} ν_{ℓ}$ via $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

Based on $10.64 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken at center-of-mass energies between 4.237 and 4.699 GeV with the BESIII detector, we study the leptonic $D_{s}^{+}$ de…

Observation of double J/ $ψ$ meson production in pPb collisions at $s_{NN}$ = 8.16 TeV

CMS Collaboration

The first observation of the concurrent production of two J/ $ψ$ mesons in proton-nucleus collisions is presented. The analysis is based on a proton-lead (pPb) data sample recorded…

Search for the Z boson decay to $τ τ μμ$ in proton-proton collisions at $s$ = 13 TeV

CMS Collaboration

The first search for the Z boson decay to $τ τ μμ$ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-m…
