1  ABREU 2000O uses leptons opposite fully reconstructed ${{\mathit D}^{*}{(2010)}^{+}}$, ${{\mathit D}^{+}}$, or ${{\mathit D}^{0}}$ mesons.
2  ABBIENDI 1999K uses the excess of right-sign over wrong-sign leptons opposite reconstructed ${{\mathit D}^{*}{(2010)}^{+}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\mathit \pi}^{+}}$ decays in ${{\mathit Z}^{0}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}$.
