Are the B decay anomalies related to neutrino oscillations?

TL;DR

This paper explores potential connections between B decay anomalies and neutrino oscillations, suggesting that lepton flavor violation in B decays may be linked to neutrino CP violation, with implications for future experiments.

Contribution

It proposes a model linking B decay anomalies to neutrino oscillation parameters, predicting correlated lepton flavor violating B decays and implications for charged lepton decays.

Findings

Predicted LFV B decay branching ratios depend on neutrino CP phase.

Possible correlation between B decay anomalies and neutrino CP violation.

Implications for charged lepton decay processes.

Abstract

Neutrino oscillations are solidly established, with a hint of CP violation just emerging. Similarly, there are hints of lepton universality violation in $b \to s$ transitions at the level of $2.6 \sigma$. 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 $\delta$ characterizing neutrino oscillations. Moreover, we also consider implications for $\ell_i \to \ell_j \ell_k \ell_k$ decays.
