| dc.description.abstract | We investigate the possibility of observing direct CP violation in the decay modes B- → D0D-s and D0D- within the standard model. Including the contributions arising from the tree, annihilation, QCD as well as electroweak penguins with both time- and space-like components, we find that the direct CP asymmetry in B- → D0D-s is very small, ∼ 0.2%, but in B- → D0D- decay it can be as large as 4%. Approximately 107 charged B mesons are required to experimentally observe the CP asymmetry parameter for the latter case. Since this is easily accessible with the currently running B-factories, the decay mode B- → D0D- may be pursued to look for CP violation. | |
