The evidence of direct CP violation in the decays D+ → Ksπ+ and D+ → KsK+ 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.

Abstract
The evidence of direct CP violation in the decays D+ → Ksπ+ and D+ → KsK+ 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.File in questo prodotto:
