On sum rules for semi-leptonic $b \to c$ and $b \to u$ decays

Wen-Feng Duan, Syuhei Iguro, Xin-Qiang Li +2

The semi-leptonic $b \to c l I^½$ processes are receiving a lot of attention, as the lepton flavor universality violation has been hinted by the measured ratios $R_{D^{(*)}} = Î(B…

Measurement of the branching fraction ratio $R_{K}$ at large dilepton invariant mass

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1138

A test of lepton universality between muons and electrons is performed using $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ decays (where $ℓ$ = $e$ , $I^¼$ ), in the dilepton invariant-mass-squared regi…
