Description

The 818 fb-1 dataset collected at the psi(3770) resonance at CLEO-c offers unique possibilities for measuring strong phase differences in neutral D decays. The measurements require that both D mesons in the event are fully reconstructed, usually with one decaying to the signal mode of interest, and the other to a CP-eigenstate. The strong phase differences extracted from these decays are important inputs to measurements of D-mixing parameters and the determination of the CKM angle gamma in B -> D K decays. Results will be presented from a variety of D decays including KS pi pi, KS K K and other 3- and 4-body modes. The impact of these results on gamma measurements will be discussed.
