Abstract

Neutrino oscillations are solidly established, with a hint of CP violation just emerging. Similarly, there are hints of lepton universality violation in bsb \to s transitions at the level of 2.6σ2.6 \sigma. By assuming that the unitary transformation between weak and mass charged leptons equals the leptonic mixing matrix measured in neutrino oscillation experiments, we predict several lepton flavor violating (LFV) B meson decays. We are led to the tantalizing possibility that some LFV branching ratios for B decays correlate with the leptonic CP phase δ\delta characterizing neutrino oscillations. Moreover, we also consider implications for ijkk\ell_i \to \ell_j \ell_k \ell_k decays.
