Dalitz plot analysis of the D + → K − K + K + decay LHCb Collaboration Alfonso Albero, Alejandro Calvo Gómez, Míriam Camboni, Alessandro Coquereau, Samuel Garrido Beltrán, Lluís Gascón Fora, David Gironella Gironell, Pere Graciani Díaz, Ricardo Graugés Pous, Eugeni Vilasis-Cardona, Xavier Marin Benito, Carla Hadrons Física de partícules Experiments Hadrons Particle physics Experiments The resonant structure of the doubly Cabibbo-suppressed decay D+→K−K+K+ is studied for the first time. The measurement is based on a sample of pp-collision data, collected at a centre-of-mass energy of 8 TeV with the LHCb detector and corresponding to an integrated luminosity of 2 fb−1. The amplitude analysis of this decay is performed with the isobar model and a phenomenological model based on an effective chiral Lagrangian. In both models the S-wave component in the K−K+ system is dominant, with a small contribution of the ϕ(1020) meson and a negligible contribution from tensor resonances. The K+K− scattering amplitudes for the considered combinations of spin (0,1) and isospin (0,1) of the two-body system are obtained from the Dalitz plot fit with the phenomenological decay amplitude. 2020-05-25T13:21:36Z 2020-05-25T13:21:36Z 2019-04-08 2020-05-25T13:21:36Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1126-6708 https://hdl.handle.net/2445/162295 696345 eng Reproducció del document publicat a: https://doi.org/10.1007/JHEP04(2019)063 Journal of High Energy Physics, 2019, p. 63 https://doi.org/10.1007/JHEP04(2019)063 info:eu-repo/grantAgreement/EC/H2020/799974/EU//FSI in hadron decays cc-by (c) LHCb Collaboration et al., 2019 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess 35 p. application/pdf Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
