abstract
We propose a method for determining $\gamma$ using $B^\pm\to D K^\pm$ decays followed by a multibody $D$ decay, such as $D \to K_S \pi^-\pi^+$, $D \to K_S K^-K^+$ and $D \to K_S \pi^-\pi^+\pi^0$. The main advantages of the method is that it uses only Cabibbo allowed $D$ decays, and that large strong phases are expected due to the presence of resonances. Since no knowledge about the resonance structure is needed, $\gamma$ can be extracted without any hadronic uncertainty.

Normalizing flows trained on D decay data create a continuous unbinned model of Dalitz plot amplitudes, allowing extraction of gamma from B decay data with successful recovery of injected values in Monte Carlo tests.
A joint fit to LHCb B to D h decays and BESIII quantum-correlated D Dbar data yields gamma = 71.3 plus or minus 5.0 degrees, the most precise measurement to date.
A novel model-independent approach with per-event phase-space weights on combined BESIII and LHCb data measures the CKM angle γ as (71.3 ± 5.0)° in B± → D(→ K0S h'+h'-) h± decays.
BESIII provides an updated model-independent measurement of strong-phase differences in D0 and bar{D}0 decays to K_S/L^0 pi^+ pi^- using quantum-correlated data, claimed to be the most precise.
The CKM angle γ is measured to be (68.1 ± 6.7)° from CP violation observed in the Dalitz plots of B± → DK± and B± → Dπ± decays with D → KS0π+π− and KS0K+K−.
