Abstract

We report the discovery of c 3055 0 , observed by its decay into the final-state D 0 , and present the first observation and evidence of the decays of c 3055 and c 3080 into D . We also perform a combined analysis of the D with the c K -and c K -decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions
