Abstract

The evidence of direct CP violation in the decays D⁺ → K_sπ⁺ and D⁺ → K_sK⁺ was analyzed by a high-statistics sample of a photoproduced charm from the FOCUS experiment. The branching ratio for the decays were measured relative to each other and to D⁺ → K^-π⁺π⁺. The relative branching ratio were improvement over earlier measurements and the measured CP asymmetries for the nodes were found to be consistent with zero.
