First measurement of A_FB and F_H in B+→π+μ+μ− decay is consistent with Standard Model predictions in both high- and low-mass dimuon regions.
No signal observed for B+ → π+ μ± e∓; branching fraction upper limit set at 1.8 × 10^{-9} at 90% CL.
LHCb reports branching fractions B(b→χ_c0,1,2 X) and B(b→η_c(2S)X)×B(η_c(2S)→φφ) plus the most precise η_c(1S) mass from φφ decays in 5.9 fb⁻¹ of data.
LHCb measures CP-violating Wilson coefficients in B0 -> K*0 mu+ mu- with higher precision than before and finds results consistent with the Standard Model.
LHCb measures forward W+ and W- production cross-sections of 1754.2 pb and 1178.1 pb at 13 TeV, agreeing with NNLO QCD predictions at higher precision than prior results.
Muon charge asymmetry from W decays is measured with highest precision in the forward region at 13 TeV and agrees with NNLO pQCD.
Upper limits of 2.9×10^{-6} for B_s^0 and 2.5×10^{-6} for B^0 on the branching fractions to J/ψγ at 90% CL, with the B_s limit improved by a factor of 2.5.
