Towards an amplitude analysis of the decay \( {\varLambda}_b^0\to {pK}^{-}\gamma \)

Abstract

The helicity formalism applied to the radiative decay \( {\varLambda}_b^0\to {pK}^{-}\gamma \) 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.

A preprint version of the article is available at ArXiv.
