The first observation and study of two new baryonic structures in the final state Ξb0π+π- and the confirmation of the Ξb(6100)- state in the Ξb-π+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 Ξb∗0, Ξb′- and Ξb∗- resonances are measured with improved precision. The new decay mode of the Ξb0 baryon to the Ξc+ π- π+ π- final state is observed and exploited for the first time in these measurements.

Abstract

The first observation and study of two new baryonic structures in the final state Ξb0π+π- and the confirmation of the Ξb(6100)- state in the Ξb-π+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 Ξb∗0, Ξb′- and Ξb∗- resonances are measured with improved precision. The new decay mode of the Ξb0 baryon to the Ξc+ π- π+ π- final state is observed and exploited for the first time in these measurements.
