Abstract

The first observation and study of two new baryonic structures in the final state Ξ0 bπþπ− 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 Ξ0 b , Ξ0−b and Ξ−b resonances are measured with improved precision. The new decay mode of the Ξ0 b baryon to the Ξ þc π− πþ π− final state is observed and exploited for the first time in these measurements.
