Abstract
Scalar leptoquark (LQs) are the prime candidates for physics beyond the Standard Model (SM) to resolve tantalizing flavor anomalies in the beauty-quark decay for both neutral- and charged-current transitions, $R_{D^{(*)}}$ and $R_{K^{(*)}}$. These same LQs can also resolve long standing tension in the muon and electron $g-2$ anomalies. These lepton flavor universality violation (LFUV) have discrepancies in the range of $2.5\sigma-4.2\sigma$. We propose a resolution to all these anomalies in a unified framework that naturally gives masses to neutrinos at the two-loop order while satisfying all the constraints from collider searches, including those from flavor physics.
