 | Raw asymmetries as a function of the decay time for (a) $B^0 \to K^+\pi^-$ and (b) $B^0_s \to K^-\pi^+$ decays. In (b), the offset $t_0=1.5$\ps corresponds to the minimum value of the decay time required by the $B^0_s \to K^-\pi^+$ event selection. The curves represent the asymmetry projections of fits to the decay time spectra. |
