What is Large direct CP violation in B→φφXs decays about?
We present a novel method to search for a new CP-violating phase in the b → s ss ss transition using B → φφX s decays, where X s represents a final state with a specific strange flavor such as K ± , K \* ± or K ± π ∓ . Direct CP violation can be enhanced due to an interference between an amplitude beyond the standard model (SM) and the SM decay amplitude through the η c resonance. We find that the CP asymmetry can be as large as 0.4 within the present experimental bounds on the b → s ss transition. These decays provide a very clean experimental signature and the background is expected to be small in particular at e + e -B factories. A simulation study for the B ± → φφK ± decay shows that the statistical significance of CP violation can exceed 5 standard deviations with 10 9 B mesons.
