A novel model-independent approach with per-event phase-space weights on combined BESIII and LHCb data measures the CKM angle γ as (71.3 ± 5.0)° in B± → D(→ K0S h'+h'-) h± decays.
No evidence for KS0 or KL0 to pi+ pi- mu+ mu- decays; first upper limits set at 1.4e-9 and 6.6e-7 (90% CL).
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.
LHCb measures f_L^d = 0.600 and f_L^s = 0.159 for B to K* Kbar* decays and reports a ratio L of 4.92 that confirms 4.4 sigma discrepancy with theory.
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.
