An analysis of B+ to DK+ and B+ to Dpi+ decays is presented where the D meson is reconstructed in the two-body final states: K+pi-, K+K-, pi+pi- and pi+K-. Using 1.0 fb-1 of LHCb data, measurements of several observables are made including the first observation of the suppressed mode B+ to DK+, D to pi+K-. CP violation in B+ to DK+ decays is observed with 5.8 sigma significance.

Search for $CP$ violation in $\Xi_c^+\to\Sigma^+h^+h^-$ and $\Lambda_c^+\to ph^+h^-$ at Belle II
hep-ex 2025-09 accept novelty 8.0 of 10
First individual A_CP measurements for Xi_c+ -> Sigma+ h+h- and Lambda_c+ -> p h+h- decays, all consistent with CP symmetry and with U-spin sum-rule predictions.

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.
