Flavour physics at CLEO-c

Abstract

Three CLEO-c results related to flavour-physics are presented: the determination of the strong-phase difference between D0->K+pi- and D0->K-pi+, delta, the measurement of the coherence parameter and average strong-phase difference between D0->K+pi-pi-pi+ and D0 -> K-pi+pi+pi- and measurements of the variation of strong-phase difference between D0 and D0bar decays to K0Spi+pi- over phase space. All measurements are important for determining the unitarity triangle angle gamma from B->D(*)K(*) decays. Furthermore, the measurement of delta is important for interpreting D0-D0bar mixing.

To be published in the proceedings of PSIPHI08, International Workshop on e+e- collisions from Phi to Psi, Laboratori Nazionali di Frascati, Italy, 7 - 10 April 2008
