The helicity formalism applied to the radiative decay Λ0b→pK−γ is presented for the first time in this paper. The aim is to provide the necessary formalism to be able to resolve the resonant pK− structures at the photon pole by means of an amplitude analysis. Experimental effects, such as resolution, are also discussed.
