Correlating the CDF $W$-boson mass shift with the $b\to s{\ell }^{+}{\ell }^{-}$ anomalies

Abstract

The recently updated measurement of the $W$-boson mass by the CDF collaboration exhibits a $7\sigma$ deviation from the SM expectation, which may imply a sign of new physics beyond the SM. The observed discrepancy could be explained by new fermions that carry the electroweak gauge charges and affect the vacuum polarization of gauge bosons. Notably, if the new fermions also have the same quantum numbers as of the SM quarks, they can mix with the latter and thus modify the penguin diagrams governing the $b\to s{\ell }^{+}{\ell }^{-}$ transitions. Therefore, the $W$-boson mass shift could be related to the $b\to s{\ell }^{+}{\ell }^{-}$ anomalies observed by the LHCb collaboration during the past few years. To investigate this possibility, we consider in this paper a model containing a vector-like top partner gauged under a new $U(1{)}^{\prime }$ symmetry. It is found that the latest CDF $m_W$ measurement and the $b\to s{\ell }^{+}{\ell }^{-}$ anomalies can be simultaneously accommodated at $2\sigma$ level.
