摘要：

Attributing the recent CLEO discovery of B --> eta' + X-s to originate (primarily) from the fragmentation of an off-shell gluon (g*) via b --> s + g*, g* --> g + eta', we emphasize that many such states (X-g) should materialize. Indeed the hadronic fragments (X-g) of g* are closely related to those seen in J/psi --> gamma(phi, omega) + X-g. A particular final state of considerable interest is X-g = K+K-. Signals from such states in B decays may be combined to provide a very sensitive search for CP violating phase(s) from nonstandard physics. The method should work even if the contribution of these source(s) to the rates is rather small (similar to 10%). [S0031-9007(97)04883-7].
