A simultaneous fit of five B meson decay modes using the z±, ξm reparameterization yields robust Gaussian behavior and a small improvement in the statistical uncertainty on the CKM angle gamma compared with combining standalone fits.

abstract
The phenomenon of CP violation is crucial to understand the asymmetry between matter and antimatter that exists in the Universe. Dramatic experimental progress has been made, in particular in measurements of the behaviour of particles containing the b quark, where CP violation effects are predicted by the Kobayashi-Maskawa mechanism that is embedded in the Standard Model. The status of these measurements and future prospects for an understanding of CP violation beyond the Standard Model are reviewed.

Study of the sensitivity to CKM angle $\gamma$ under simultaneous determination from multiple $B$ meson decay modes
A simultaneous fit of five B meson decay modes using the z±, ξm reparameterization yields robust Gaussian behavior and a small improvement in the statistical uncertainty on the CKM angle gamma compared with combining standalone fits.
