Observation of $D \to K ˉ_{1} (1270) μ^{+} ν_{μ}$ and test of lepton flavor universality with $D \to K ˉ_{1} (1270) ℓ^{+} ν_{ℓ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

By analyzing 7.93 $f b^{- 1}$ of $e^{+} e^{-}$ collision data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report t…

First measurement of the $C P$ -violating phase in $B_{s}^{0} \to J / ψ (\to e^{+} e^{-}) ϕ$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +954

A flavour-tagged time-dependent angular analysis of $B_{s}^{0} \to J / ψ ϕ$ decays is presented where the $J / ψ$ meson is reconstructed through its decay to an $e^{+} e^{-}$ pair. The analysis u…
