Abstract

We analyze a sample of 3×106 quantum-correlated D0D^̄0 pairs from 818pb^-1 of e⁺e^- collision data collected with the CLEO-c detector at E_cm=3.77GeV, to give an updated measurement of cos δ and a first determination of sin δ, where δ is the relative strong phase between doubly Cabibbo-suppressed D0→K⁺π^- and Cabibbo-favored D ^̄0→K⁺π^- decay amplitudes. With no inputs from other experiments, we find cos δ=0.81-0.18-0.05+0.22+0.07, sin δ=-0.01±0.41±0.04, and |δ|=(10-53-0+28+13)°. By including external measurements of mixing parameters, we find alternative values of cos δ=1.15-0.17-0.08+0.19+0.00, sin δ=0.56-0.31-0.20+0.32+0.21, and δ=(18-17+11)°. Our results can be used to improve the world average uncertainty on the mixing parameter y by approximately 10%.
