Forward-backward $b$-quark asymmetry at the Z pole: QCD uncertainties redux

The forward-backward asymmetry of b-quarks measured at LEP in e + e − collisionsat the Z pole, A 0,b fb | exp = 0.0992 ± 0.0016, remains today the electroweakprecision observable with the largest disagreement (2.8σ) with the StandardModel theoretical prediction, A 0,b fb | th = 0.1037 ± 0.0008. The...
