Desperately Seeking Non-Standard Phases via Direct CP Violation in $b\to sg^\ast$ Process

Abstract

Attributing the recent CLEO discovery of $B \to η' + X_s$ to originate (primarily) from the fragmentation of an off-shell gluon ($g^*$) via $b \to s + g^*$, $g^* \to g + η'$, we emphasize that many such states ($X_g$) should materialize. Indeed the hadronic fragments ($X_g$) of $g^*$ states are closely related to those seen in $ψ\to γ(ϕ, ω) + X_g$. 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 ($\sim10%$) to the point that a comparison between theory and experiment may find it extremely difficult to reveal the presence of such a new physics.
