Description

The Muon $g-2$ experiment at Fermilab has recently announced its measurement of the muon anomalous magnetic moment (AMM), which is in complete agreement with the long-standing tension previously reported by BNL. In addition, recent precise measurement of the fine-structure constant at Berkeley Lab shows somewhat disagreement with the electron AMM. Besides, evidence
for lepton flavor universality violation in beauty-quark decays both in neutral- and charged-current transitions have been persistently observed in several experiments, and LHCb's recently updated result is in full concordance. These tantalizing flavor anomalies have discrepancies in the range $2.5\sigma-4.2\sigma$, strongly indicating that maybe the Standard Model of particle physics is finally cracking. In this work, we propose a resolution to all these anomalies within a unified framework that is directly linked to the origin of neutrino mass. Our proposed scenario utilizes two TeV scale scalar leptoquarks to address four major flavor anomalies, while satisfying all constraints from collider searches, including the constraints from flavor physics.
