Title:    Precise determination of the unitarity triangle
SubTitle: LHCb and the essential role of CLEOc

Abstract: The LHCb experiment will be introduced. The precise determination of gamma is a cornerstone of the LHCb physics programme; the motivation for this will be presented. Decays of the type B+ -> DK+, where the D is a D0 or a D0bar decaying to the same final state, allow a theoretically clean measurement of gamma. The prospects with LHCb for modes where the D decays to 2, 3 and 4 bodies are discussed. This discussions introduces the importance of measurements of the strong parameters of the relevent D-decays to allow precise determination of gamma and the crucial role played by quantum correlated e+e- -> psi(3770) ->D0D0bar data currently being collected by CLEOc. The CLEOc measurements essential to a precise determination of gamma are presented.
