Desperately Seeking Non-Standard Phases via Direct CP Violation in $b\to s{g}^{\ast }$ Process

Abstract

Attributing the recent CLEO discovery of $B\to {\eta }^{\prime }+X_s$ to originate (primarily) from the fragmentation of an off-shell gluon ($g^{\ast }$) via $b\to s+g^{\ast }$, $g^{\ast }\to g+{\eta }^{\prime }$, we emphasize that many such states ($X_g$) should materialize. Indeed the hadronic fragments ($X_g$) of $g^{\ast }$ states are closely related to those seen in $\psi \to \gamma (\varphi ,\omega )+X_g$. A particular final state of considerable interest is $X_g=K^{+}{K}^{-}$. Signals from such states in $B$ decays can be combined to provide a very sensitive search for CP violating phase(s) from non-standard physics. The method should work even if the contribution of these source(s) to the rates is rather small ($\sim 10$) to the point that a comparison between theory and experiment may find it extremely difficult to reveal the presence of such a new physics.
