Abstract
After the long-standing mismatch between ALR and AFBb measurements for predicting the Higgs boson mass, the recent and very precise result on Mw confirms the existence of a crisis in the sector of electroweak measurements. In this note, it is shown that ALR and Mw can be simply reconciled by assuming a common value for the T parameter. Consequently, the AFBb deviation is amplified and reaches a 4 s.d. significance. Interpreting this as evidence for a non-universal behaviour of the b quark is proposed within an extra dimension model. Large deviations with respect to the SM are expected at future Z factories.
