Study of the sensitivity to CKM angle γ under simultaneous determination from multiple B meson decay modes

Several methods exist to measure CP violation observables related to the CKM unitarity triangle angle γ using B meson decays. These observables are different for every B meson decay considered, although the information they contain on γ is encoded in a similar way for all of them. This paper describ...

Zusammenfassung:Several methods exist to measure CP violation observables related to the CKM unitarity triangle angle γ using B meson decays. These observables are different for every B meson decay considered, although the information they contain on γ is encoded in a similar way for all of them. This paper describes a strategy for a simultaneous measurement of γ using several B meson decays that takes into account possible correlations between them based on the methodologies described in [J. Garra Ticó, arXiv:1804.05597]. Sensitivity studies demonstrate that the simultaneous analysis of several B meson decay modes results in smaller uncertainties and improved statistical behavior compared to a combination of standalone measurements.
