| dc.description | We report on a direct measurement of the mixing parameter y=(3.42+-1.39+-0.74)% in the D0-D0bar system by measuring the lifetime difference between the CP mixed final state K^+pi^- and the CP even state K^+K^-. We also present a study of the decay \ws based on a sample of 149+-31 observed events compared to 36760+-195 events observed in the Cabibbo favored channel D0->K^-pi^+. The observed branching ratio R=(0.404+-0.085+-0.025)% is used to obtain limits on the mixing parameters x' and y' and the doubly Cabibbo suppressed branching ratio, R_DCS. These studies are based on a large sample of photoproduced charm mesons from the FOCUS experiment at Fermilab (FNAL-E831). | |
