We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons (electron and muon) and B-physics anomalies (R-K(*) and R-D(*)). The model consists of SU(2)(L) singlet leptoquark S-1 similar to ((3) over bar, 1, 1/3), doublet leptoquark (R) over tilde (2) similar to (3, 2, 1/6) and triplet leptoquark S-3 ((3) over bar, 3, 1/3). We combine the constraints arising from the low-energy lepton flavor violation, meson decay and mixing observables. We perform a detailed phenomenological analysis and identify the minimized texture of leptoquark Yukawa matrices to accommodate a unified explanation of the anomalies and neutrino oscillation data.
