      abstract     = {The first observation of the decay $B^0 \rightarrow D^0
                      \overline{D}{}^0 K^+ \pi^-$ is reported using proton-proton
                      collision data corresponding to an integrated luminosity of
                      4.7 fb$^{-1}$ collected by the LHCb experiment in 2011, 2012
                      and 2016. The measurement is performed in the full
                      kinematically allowed range of the decay outside of the
                      $D^{*-}$ region. The ratio of the branching fraction
                      relative to that of the control channel $B^0→D^{*-}D^0K^+$
                      is measured to be $R$=(14.2±1.1±1.0)\%, where the first
                      uncertainty is statistical and the second is systematic. The
                      absolute branching fraction of $B^0 \rightarrow D^0
                      \overline{D}{}^0 K^+ \pi^-$ decays is thus determined to be
                      $B$($B^0 \rightarrow D^0 \overline{D}{}^0 K^+
                      \pi^-$)=(3.50±0.27±0.26±0.30)×10$^{-4}$, where the third
                      uncertainty is due to the branching fraction of the control
                      channel. This decay mode is expected to provide insights to
                      spectroscopy and the charm-loop contributions in rare
                      semileptonic decays.},
