Abstract
[Abstract] The first observation and study of two new baryonic structures in the final state Ξ0bπþπ− and the confirmation of the Ξbð6100Þ− state in the Ξ−b πþπ− decay mode are reported using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb−1. In addition, the properties of the known Ξ 0 b , Ξ0−b and Ξ −b resonances are measured with improved precision. The new decay mode of the Ξ0b baryon to the Ξþcπ− πþ π− final state is observed and exploited for the first time in these measurements.
