Interpreting the $W$ mass anomaly in the vectorlike quark models

Abstract

The new measurement of $W$-boson mass from the CDF collaboration depicts a remarkable $7\sigma$ disagreement with the Standard Model (SM) prediction. This highly implies that there exist new particles or fields beyond the SM. In this work, we explore the possibility of explaining the $W$ mass anomaly in the simple extension of the SM with the vector-like quarks. Confronting with the current LHC data and the electroweak precision measurements, we find that the vector-like quark models can reconcile SM theory with the $W$ mass anomaly
