First measurement of suppressed B- -> D0 K- decays through the ADS method in hadron collisions

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.

First measurement of ADS parameters using B- -> D0K- decays in hadron collisions

Measurements of branching fractions and CP-asymmetries of B^{-} \rightarrow D^{0}K^{-} modes allow a theoretically-clean extraction of the CKM angle γ. The method proposed by Atwood, Dunietz and Soni (ADS) makes use of a decay chain where color and Cabibbo suppression interfere, which produces large CP-violating asymmetries. The CDF experiment reports the first measurement at a hadron collider of branching fractions and CP-asymmetries of suppressed B^{-} \rightarrow D^{0}h^{-} signals, where h is πor K. Using 5.0 fb^{-1} of data we found a combined significance exceeding 5σand we determined the ADS parameters with accuracy comparable with B-factories.
