Abstract
A systematic experimental search for two-body hadronic decays of the b quark of the type b --> quark + meson is proposed. These reactions ha ve a well-defined experimental signature and they should be theoretica lly cleaner compared to exclusive decays. Many modes have appreciable branching ratios, and partial rate asymmetries may also be quite large (about 8%-50%) in several of them. In a few cases electroweak penguin s appear to be dominant and may be measurable. CP-violating triple cor relation asymmetries provide a clean test of the standard model. [S003 1-9007(98)07437-7].
