Evidence of a J/psi Lambda structure and observation of excited Xi(-) states in the Xi(-)(b) -> J/psi Lambda K- decay.
SCIENCE BULLETIN, 66 (13).
pp. 1278-1287.
Abstract
First evidence of a structure in the J/ψΛ invariant mass distribution is obtained from an amplitude analysis of Ξ<sub>b</sub><sup>-</sup>→J/ψΛK<sup>-</sup> decays. The observed structure is consistent with being due to a charmonium pentaquark with strangeness with a significance of 3.1σ including systematic uncertainties and look-elsewhere effect. Its mass and width are determined to be 4458.8±2.9<sub>-1.1</sub><sup>+4.7</sup>MeV and 17.3±6.5<sub>-5.7</sub><sup>+8.0</sup>MeV, respectively, where the quoted uncertainties are statistical and systematic. The structure is also consistent with being due to two resonances. In addition, the narrow excited Ξ<sup>-</sup> states, Ξ1690<sup>-</sup> and Ξ1820<sup>-</sup>, are seen for the first time in a Ξ<sub>b</sub><sup>-</sup> decay, and their masses and widths are measured with improved precision. The analysis is performed using pp collision data corresponding to a total integrated luminosity of 9 fb<sup>-1</sup>, collected with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV.
