The first observation of the decays Λ[superscript 0][subscript b] →χ[subscript c1]pK[superscript -] and Λ[superscript 0][subscript b] →χ[subscript c2]pK[superscript -] is reported using a data sample corresponding to an integrated luminosity of 3.0 fb[superscript -1], collected by the LHCb experiment in pp collisions …
