Abstract
We point out the necessity to consider -decay observables in resolutions of the -boson anomaly in the Standard Model Effective Field Theory that go beyond pure oblique corrections. We demonstrate that present global analyses that explain the -boson mass anomaly predict a large, percent-level, violation of first-row CKM unitarity. We investigate what solutions to the -boson mass anomaly survive after including -decay constraints.
