A bstractIn light of the discovery of a Higgs-like particle at the LHC, we revisit the status of the precision electroweak data, focusing on two discrepant observables: 1) the long-standing 2.4σ deviation in the forward-backward asymmetry of the bottom quark $A_{\mathrm{FB}}^b$, and 2) the 2.3σ deviation in Rb, the ratio of the $Z\ \to\ b\overline{b}$ partial width to the inclusive hadronic width, which is now in tension after a recent calculation including new two-loop electroweak… Expand
