Abstract

Results are reported from an amplitude analysis of the B+ → D+ D− K+ decay. The analysis is carried out using LHCb proton-proton collision data taken at √s = 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb^−1. In order to obtain a good description of the data, it is found to be necessary to include new spin-0 and spin-1 resonances in the D− K+ channel with masses around 2.9 GeV/c^2, and a new spin-0 charmonium resonance in proximity to the spin-2 χc2(3930) state.
