First observation of suppressed B- -> D0 K- decays in hadron collisions
Abstract
We report the first measurement of branching fractions and CP-violating asymmetries of suppressed B- -> DK- decays in hadron collisions, using the approach proposed by Atwood, Dunietz, and Soni (ADS) to determine the CKM angle gamma in 7.0 fb^-1 of data. The ADS parameters are determined with accuracy comparable with B-factory measurements and significantly improve the global knowledge of the angle gamma.
