Abstract
Abstract Gronau and Wyler (GW) extract the weak phase γ and remove the dependence on final state phases by measuring six charged B meson rates, which are grouped into two triangles. This note applies the GW method to self-tagging B d modes. Self-tagging eliminates the need for time-dependent measurements. Of interest are the six rates, (Γ( B d → D 0 K ∗0 )=Γ( B d → D 0 K ∗0 , Γ( B d → D 0 K ∗0 =Γ( B d → D 0 K ∗0 , Γ( B d → D 0 CP K ∗0 and Γ( B d → D CP 0 K ∗0 , where D CP 0 denotes a CP eigenmode of a D 0 or D 0 . Here the K ∗0 must be seen in its K + π − mode, which tags the beauty flavour. An additional handle exists to resolve an ambiguity in |sin γ|, which i...
