We calculate final-state interaction corrections to the energy-angular distribution of l^+ in semi-leptonic top quark decay, where the parent top quark is produced via e^+e^- -> t\bar{t} near threshold. These are the corrections due to…

The sign of $A_{\rm CP}(K^-\pi^+) < 0$, the evidence for $\bar B^0 \to \pi^0\pi^0$, and the possibly sizable $A_{\pi\pi}$ and $S_{\pi\pi}$ in $\bar B^0 \to \pi^+\pi^-$ all suggest that final state rescattering may be needed in $\bar B\to…

The newly observed $\bar B^0 \to \bar K^0\pi^0$ mode is quite sizable while $\pi^-\pi^+$ is rather small. Data also hint at $\pi^-\pi^0 \gtrsim \pi^-\pi^+$. Though consistent with zero, central values of CP violating asymmetries in…
