Abstract
A data set corresponding to an integrated luminosity of $9 \text{fb}^{-1}$ of
proton-proton collisions collected by the LHCb experiment has been analysed to
search for $B_c^+ \to D^{(*)+}_{(s)} \overset{\scriptstyle (-)}{D}{}^{(*)0}$
decays. The decays are fully or partially reconstructed, where one or two
missing neutral pions or photons from the decay of an excited charm meson are
allowed. Upper limits for the branching fractions, normalised to $B^+$ decays
to final states with similar topologies, are obtained for fourteen $B_c^+$
decay modes. For the decay $B_c^+ \to D_s^+ {\overline{D}}^0$, an excess with a
significance of 3.4 standard deviations is found.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
