Z→b¯bDecay Asymmetry: Lose-Lose for the Standard Model

Combining precision measurements and the Higgs boson search limit, the electroweak data have evolved to a point where new physics is favored whether the $3.2\sigma$ $A_{\mathrm{FB}}^b$ anomaly is genuine or not. Such new physics could greatly alter the inferred value of the Higgs boson mass.
