Título: | Amplitude analysis of the B+ →d+D-K+ decay |
Autor: | LHCb Collaboration; García Martín, L.M.; Henry, L.; Jashal, B.; Martínez-Vidal, Fernando CSIC ORCID; Oyanguren, Arantza CSIC ORCID; Remón Alepuz, Clara; Ruiz Vidal, Joan; Sánchez Mayordomo, Carlos CSIC | Fecha de publicación: | dic-2020 | Citación: | Physical Review D 102: 112003 (2020) | Resumen: | 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 χc2(3930) state. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevD.102.112003 | URI: | http://hdl.handle.net/10261/230446 | DOI: | 10.1103/PhysRevD.102.112003 | Identificadores: | doi: 10.1103/PhysRevD.102.112003 issn: 2470-0029 |
