Abstract

We report the result of a search for D⁰ D^{¯ 0} mixing in the data from hadroproduction experiment E791 at Fermilab. We use the charge of the pion from the strong decay D*⁺ → D⁰_π+(and charge conjugate) to identify the charm quantum number of the neutral D at production, and the charge of the lepton and the kaon in the semileptonic decays D⁰ → Kev and Kμv to identify the charm at the time of decay. No evidence of mixing is seen. We set a 90% confidence level upper limit on mixing of r<0.50%, where r = γ(D⁰ D^{¯ 0} → K⁺l⁻ v_l)/γ(D⁰ → K⁺l⁻ v_l).
