Abstract

The first observation of two structures consistent with resonances in the final states Λ0b π− and Λ0b π+ is reported using samples of pp collision data collected by the LHCb experiment at √s = 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb^−1. The ground states Σb± and Σb*± are also confirmed and their masses and widths are precisely measured.
