Description
We report a measurement of the branching fraction of $B^0 \rightarrow D^+ D^-$ decays. The result is based on a data sample that contains $535\times10^6$ $B\bar B$ pairs collected on the $\Upsilon(4S)$ resonance with the Belle detector at the asymmetric-energy KEKB $e^+ e^-$ collider. We obtain $(2.32\pm0.25\pm0.29)\times10^{-4}$ for the branching fraction of $B^0 \rightarrow D^+ D^-$ decays,
which is in agreement with previous measurements.
