abstract

We analyse $D$ decays to two pseudoscalars $(\pi,K)$ assuming the dominant source of $\mathrm{SU}(3)_F$ breaking lies in final state interactions. We obtain an excellent agreement with experimental data and are able to predict CP violation in several channels based on current data on branching ratios and $\Delta \mathrm{A_{CP}}$. We also make predictions for $\delta_{K\pi}$ and the branching fraction for the decay $D_s^+\to K^+K_L$.

  1. Measurement of the CP asymmetry in $D^+ \to \pi^+ \pi^0$ decays at Belle II

    hep-ex 2025-06 accept novelty 5.0 of 10

    The new world-best measurement of the CP asymmetry in D+ -> pi+ pi0 decays is (-1.8 +/- 0.9 +/- 0.1)%, consistent with zero and with the Standard Model.
