LHCb reports the first upper limits on B0 → K+π−τ+τ− and Bs0 → K+K−τ+τ− branching fractions, with recast limits of 2.8×10−4 on B0 → K*(892)0 τ+τ− at 95% CL that improve prior bounds by an order of magnitude.

No signal observed for B+ → π+ μ± e∓; branching fraction upper limit set at 1.8 × 10^{-9} at 90% CL.
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.
