Study of the sensitivity to CKM angle γ under simultaneous determination from multiple B meson decay modes
read the original abstract
Several methods exist to measure $CP$ violation observables related to the CKM unitarity triangle angle $\gamma$ using $B$ meson decays. These observables are different for every $B$ meson decay considered, although the information they contain on $\gamma$ is encoded in a similar way for all of them. This paper describes a strategy for a simultaneous measurement of $\gamma$ using several $B$ meson decays that takes into account possible correlations between them. Sensitivity studies demonstrate that the simultaneous analysis of several $B$ meson decay modes results in smaller uncertainties and improved statistical behaviour compared to a combination of standalone measurements.

Measurement of $\gamma$ using $B^{\pm}\rightarrow DK^{\pm}$ and $B^{\pm}\rightarrow D\pi^{\pm}$ decays with $D\rightarrow K_{\rm S}^{0}\pi^{+}\pi^{-}$ and $D\rightarrow K_{\rm S}^{0}K^{+}K^{-}$
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−.
