Exploring CP violation with B < inf > s < /inf > < sup > 0 < /sup > →D̄ < sup > 0 < /sup > φ decays

Abstract

We note that it is possible to determine the weak phase γ from the time dependent measurements of the decays Bs0(t) (B̄s0(t))→D̄0φ without any hadronic uncertainties. These decays are described by the color suppressed tree diagrams and hence are free from the penguin pollutions. We further demonstrate that γ can also be extracted with no hadronic uncertainties from an angular analysis of corresponding vector vector modes, Bs0(t)((B̄s0(t)))→D̄ *0φ. Although the branching ratios for these decay modes are quite small O(10-5 -10-6), the strategies presented here appear to be particularly interesting for the "second generation" experiments at hadronic B factories. © 2002 The American Physical Society.
