Description

We explore the possibility of resolving the $W$ mass shift observed by the CDF collaboration and the apparent deviation from unitarity in the first row of the CKM matrix simultaneously in a class of left-right symmetric models with universal seesaw. A unique non-trivial solution to the two anomalies was obtained, where the down quark mixing with vector-like quarks~(VLQ) resolves the CKM unitarity problem, while top mixing with VLQ explains the positive shift in $W$ mass. This leads to testable predictions in the model.
