Abstract
We present an economical model where an S1 leptoquark and an anomaly-free U(1)X gauge symmetry with X = B3− 2Lμ/3 − Lτ/3 are introduced, to account for the muon anomalous magnetic moment aμ≡ (gμ− 2) and flavor puzzles including $$ {R}_{K^{\left(\ast \right)}} $$

anomaly. Meanwhile, the specific flavor mixing patterns of quarks and leptons can be generated after the spontaneous breakdown of the U(1)X gauge symmetry via the Froggatt-Nielsen mechanism. The S1 leptoquark which is also charged under the U(1)X gauge symmetry can simultaneously explain the latest muon (g − 2) result and the $$ {R}_{D^{\left(\ast \right)}} $$
