Measurement of the CKM Angles {alpha} and {gamma} at the BABAR Experiment
- SLAC
The primary objective of the BABAR Experiment is to test the Standard Model explanation of CP violation in weak decays by over-constraining the CKM Unitarity Triangle. This includes the measurement of all three angles of the triangle. Although precise measurements of the angle {beta} have been obtained using B decays to charmonium states, the remaining angles, {alpha} and {gamma}, pose greater experimental challenges. In this paper, the latest measurements of modes which will constrain {alpha} and {gamma} will be presented, including B{sup 0} --> {rho}{sup +}{rho}{sup -} for {alpha} and a measurement of sin(2{beta} + {gamma}) from the B{sup 0} --> D(*){sup {+-}}{pi}{sup {-+}} system.
