“…• A FB (b), the forward-backward asymmetry into b quarks, has the value 0.0994 (17), which is 2.6σ below the standard model global fit value of 0.1038 (8). On the other hand, the SLD value for the related quantity A b = 0.922 (20) (see the appendices in [8] for the definitions) is only 0.6σ below the expected 0.9347 (1), and the hadronic branching fraction R b = 0.2165 (7), which at one time appeared anomalous, is now only 1.1σ above the expectation 0.2157 (2). If not just a statistical fluctuation or systematic problem, A FB (b) could be a hint of new physics.…”
