Abstract

We measure the CP-violating asymmetries in decays to the D⁰ → K⁺ K^- and D⁰ → π⁺ π^- CP eigenstates using 540 fb^-1 of data collected with the Belle detector at or near the Υ{hooked} (4 S) resonance. Cabibbo-favored D⁰ → K^- π⁺ decays are used to correct for systematic detector effects. The results, A_CP^{K K} = (- 0.43 ± 0.30 ± 0.11) % and A_CP^{π π} = (+ 0.43 ± 0.52 ± 0.12) %, are consistent with no CP violation.
