Z --> b macro b decay 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(b)(FB) anomaly is genuine or not. Such new physics could greatly alter the inferred value of the Higgs boson mass.
