Description

Recently, the CDF collaboration has reported a substantial $7\sigma$ deviation of the W-boson mass from the Standard Model (SM) prediction. Furthermore, the Muon g-2 Experiment recently confirmed the longstanding tension in $(g −2)_{\mu}$. Besides, the updated result from the LHCb collaboration found evidence for the breaking of lepton universality in beauty-quark decays, which shows a $3.1\sigma$ discrepancy and is consistent with their previous measurements. Motivated by several of these drawbacks of the SM, 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 $(g −2)_{\mu}$, 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.
