Abstract

Strategies that utilise the interference effects within B -> DK decays hold great potential for improving our sensitivity to the CKM angle gamma. However, in order to exploit fully this potential, knowledge of parameters associated with the D decay, such as strong-phase differences, are required. This essential information can be obtained from the unique quantum-correlated psi(3770) datasets at CLEO-c. Results of such analyses involving the decay modes D -> Kpi, Kpipi⁰, Kpipipi and K⁰_Spipi will be presented.
