Abstract / Description of output

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/𝑐2, and a new spin-0 charmonium resonance in proximity to the spin-2 𝜒𝑐⁢2⁡(3930) state.
