Search for $C P$ violation in $D^{+} \to ϕ π^{+}$ decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1106

A search for charge-parity ( $C P$ ) violation in the Cabibbo-suppressed $D^{+} \to ϕ π^{+}$ decay is presented, using proton-proton collision data corresponding to an integrated luminos…

Proof of principle for nucleon polarization measurement at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +754

A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using $10.09 \times 1 0^{9}$ $J / ψ$ events at BESIII, the…

Differential measurement of the branching fraction and $C P$ asymmetry of the decay $B^{\pm} \to π^{\pm} μ^{+} μ^{-}$

LHCb collaboration, R. Aaij, M. Abdelfatah +1121

Differential measurements of the branching fraction and $C P$ asymmetry of the decay $B^{\pm} \to π^{\pm} μ^{+} μ^{-}$ are performed in intervals of the dimuon mass squared, $q^{2}$ , using pro…

Search for the lepton-flavour-violating decays $B^{0} \to K^{* 0} τ^{\pm} e^{\mp}$

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1131

A first search for the lepton-flavour-violating decays $B^{0} \to K^{* 0} τ^{\pm} e^{\mp}$ is presented. The analysis is performed using a sample of proton-proton collision data, collected…
