Combination of gamma measurements from BaBar
Denis Derkach (for the BaBar Collaboration)
TL;DR
This paper combines gamma angle measurements from BaBar, providing a refined value that confirms CP violation with high significance, surpassing previous results.
Contribution
It presents a combined analysis of BaBar data to improve the precision of the CKM gamma angle measurement, updating previous results.
Findings
Gamma angle measured as 69+17-16 degrees
Results show CP violation at 5.9 sigma significance
Supersedes previous BaBar measurements
Abstract
We present the combination of the CKM angle gamma measurements performed by the BaBar experiment at the PEP-II e+e- collider at SLAC National Laboratory. The analysis supersedes previous results obtained by collaboration and gives gamma=69+17-16 degrees modulo 180 degrees. The results are inconsistent with the absence of CP violation at a significance of 5.9 standard deviations
