Observation of new baryons in the Ξ_b^-π^+π^- and Ξ_b^0π^+π^- systems

The first observation and study of two new baryonic structures in the final state \Xi_b^0\pi^+\pi^- and the confirmation of the \Xi_b(6100)^- state in the \Xi_b^-\pi^+\pi^- decay mode are reported using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9\mathrm{fb}^{-1}. In addition, the properties of... Show more
