A unified explanation of $b \to s \mu^+ \mu^-$ anomalies, neutrino masses and $B\rightarrow \pi K$ puzzle

Understand

Anomalies in semi-leptonic $B$ decays could indicate new physics beyond the standard model(SM).

• There is an older puzzle in non-leptonic $B \to \pi K$ decays.
• The new particles, leptoquarks and diquarks, required to solve the semi-leptonic and the non-leptonic puzzles can also generate neutrino masses and mixing at loop level.
• We show that a consistent framework to explain the $B$ anomalies and the neutrino masses is possible and we make predictions for certain rare nonleptonic $B$ decays.
