Abstract

Results are reported from an amplitude analysis of the Bþ → DþD−Kþ decay. The analysis is carriedout using LHCb proton-proton collision data taken at ffiffis p ¼ 7, 8, and 13 TeV, corresponding to a totalintegrated luminosity of 9 fb−1. In order to obtain a good description of the data, it is found to be necessaryto include new spin-0 and spin-1 resonances in the D−Kþ channel with masses around 2.9 GeV=c2, and anew spin-0 charmonium resonance in proximity to the spin-2 χc2ð3930Þ state.
