The Ratio of the Rare D0 Decay Mode

Caption: The ratio of the rare D0 decay mode (K+pi-) to a more common one (K-pi+) versus decay time, measured in units of the D0 lifetime. If the mixing process did not occur, the ratio would remain unchanged with time. The measured ratio includes decays from prompt and non-prompt D0 mesons (blue curve). The ratio using only prompt decays is shown by the red curve.
