Unified explanation of $b\rightarrow s\mu\mu$ anomalies, neutrino masses and $B \rightarrow \pi K$ puzzle.

Anomalies in semileptonic B decays could indicate new physics beyond the standard model (SM). There is an older puzzle in nonleptonic $B \rightarrow \pi K$ decays. The new particles, leptoquarks and diquarks, required to solve the semileptonic and the nonleptonic 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.
