Attributing the recent CLEO discovery of B→η′+Xs to originate (primarily) from the fragmentation of an off-shell gluon (g*) via b→s+g*, g*→g+η′, we emphasize that many such states (Xg) should materialize. Indeed the hadronic fragments (Xg) of g* are closely related to those seen in J/ψ→γ(φ, ω)+Xg. A particular final state of considerable interest is Xg = 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 (∼10%).
