Observation of two resonances in the [lambda]0b π± systems and precise measurement of [sigma]±b and [sigma][star] ±b properties
The first observation of two structures consistent with resonances in the final states Λ0bπ− and Λ0bπ+ 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 Σ±b and Σ*±b are also confi...
