LHCb observes 3.2 sigma evidence for B+ -> pi+ e+ e- with measured branching fraction (2.4 +0.9 -0.8 +0.4 -0.2) x 10^-8, consistent with Standard Model.
A new charm-strange resonance D_s1(2933)^+ with J^P=1^+ is observed at >10 sigma in B^0 to D+ D- K+ pi- decays, with measured mass 2933 MeV and width 72 MeV.
First observation of χ_c1(3872) → J/ψ μ⁺μ⁻ reported at 6.5σ significance with branching fraction ratio (1.68 ± 0.37) × 10^{-3} relative to the π⁺π⁻ mode.
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.
