Abstract
Very recently, a substantial $7\ensuremath{\sigma}$ deviation of the $W$-boson mass from the Standard Model prediction has been reported by the CDF Collaboration. Furthermore, the Muon $g\ensuremath{-}2$ Experiment recently confirmed the long-standing tension in $(g\ensuremath{-}2{)}_{\ensuremath{\mu}}$. Besides, the updated result from the LHCb Collaboration found evidence for the breaking of lepton universality in beauty-quark decays, which shows a $3.1\ensuremath{\sigma}$ discrepancy and is consistent with their previous measurements. Motivated by several of these drawbacks of the Standard Model, in this work, we propose a model consisting of two scalar leptoquarks and a vectorlike quark to simultaneously address the $W$-boson mass shift, the $(g\ensuremath{-}2{)}_{\ensuremath{\mu}}$, and anomalies in the neutral current transitions of the $B$-meson decays. The proposed model also sheds light on the origin of neutrino mass and can be fully tested at the future colliders.
