A search for decays of Bc+ mesons to two charm mesons is performed for the first time using data corresponding to an integrated luminosity of 3.0 fb− 1, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. The decays considered are Bc+→ D (s)(⁎)+ D‾(⁎) 0 and Bc+→ D (s)(⁎)+ D (⁎) 0, which are normalised to high-yield B+→ D (s)+ D‾ 0 decays. No evidence for a signal is found and limits are set on twelve Bc+ decay modes.
