CPT Student Seminar: New physics at tree level decays and its implications in the precision of the CKM phase $\gamma$

Presented by Gilberto Tetlalmatzi-Xolocotz, Durham University

12 January 2015 17:00 in OC218

In this talk the assumption that no new physics is acting in tree-level B-meson decays will be reviewed. The consequences of beyond standard model tree level effects allowed by current experimental data for the precision in the direct determination of the CKM angle $\gamma$ will be also discussed. Interestingly tree level deviations consistent with the experimental measurements available nowadays lead to a non negligible intrinsic uncertainty $\delta \gamma \approx \pm 4^{\circ}$, which can affect the sensitivity expected by LHCb and Belle II for the determination of this observable in the near future.
