Abstract The B+DK+π+ decay potentially provides an excellent way to investigate charm meson spectroscopy. The decay is searched for in a sample of proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3fb1. A clear signal is observed, and the ratio of its branching fraction to that of the B+Dπ+π+ normalisation channel is measured to be B(B+DK+π+)B(B+Dπ+π+)=(6.39±0.27±0.48)×102, where the first uncertainty is statistical and the second is systematic. This is the first observation of the B+DK+π+ decay.
