Observation of two resonances in the Λ_{b}^{0}π^{±} systems and precise measurement of Σ_{b}^{±} and Σ_{b}^{*±} properties

The first observation of two structures consistent with resonances in the final states Λ_{b}^{0}π^{-} and Λ_{b}^{0}π^{+} is reported using samples of pp collision data collected by the LHCb experiment at sqrt[s]=7 and 8 TeV, corresponding to an integrated luminosity of 3  fb^{-1}. The ground states...
