title = "Observation of New Baryons in the Ξ − b π + π − and Ξ 0 b π + π − Systems",
abstract = "The first observation and study of two new baryonic structures in the final state Ξ0 bπ{\th}π− and the confirmation of the Ξb{\dh}6100{\TH}− state in the Ξ− b π{\th}π− 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 {\th}c π− π{\th} π− final state is observed and exploited for the first time in these measurements.",
