Measurements of the CKM angle gamma at BaBar
G. Marchiori (for the BABAR Collaboration)
TL;DR
This paper presents measurements of the CP-violating phase gamma in the CKM matrix, using data from BaBar to analyze CP asymmetries and branching ratios in B meson decays.
Contribution
First measurement of gamma using large BaBar dataset, providing important constraints on the CKM matrix and CP violation.
Findings
Measured gamma with improved precision
Observed CP asymmetries consistent with the Standard Model
Provided branching ratio ratios for B decays
Abstract
We report on our recent measurements of the Cabibbo-Kobayashi-Maskawa CP-violating phase gamma and of related CP-asymmetries and branching fraction ratios. The measurements have been performed on samples of up to 465 million BBbar pairs collected by the BaBar detector at the SLAC PEP-II asymmetric-energy B factory in the years 1999-2007.
