Search for $B_c^{+}$ decays to two charm mesons

Abstract

A search for decays of $B_c^{+}$ 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 $B_c^{+}\to D_{(s)}^{(\ast )+}{\overline{D}}^{(\ast )0}$ and $B_c^{+}\to D_{(s)}^{(\ast )+}{D}^{(\ast )0}$, which are normalised to high-yield $B^{+}\to D_{(s)}^{+}{\overline{D}}^0$ decays. No evidence for a signal is found and limits are set on twelve $B_c^{+}$ decay modes.
