Abstract

The first observation and study of two new baryonic structures in the final state Ξ0bπ+π− and the confirmation of the Ξb(6100)− state in the Ξ−bπ+π− decay mode are reported using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9fb−1. In addition, the properties of the known Ξ∗0b, Ξ′−b and Ξ∗−b resonances are measured with improved precision. The new decay mode of the Ξ0b baryon to the Ξ+cπ−π+π− final state is observed and exploited for the first time in these measurements.
