Search for Bc + decays to two charm mesons

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 3.0fb−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.
