Resumen

The resonant structure of the radiative decay Λ_b⁰→pK⁻γ in the region of proton-kaon invariant-mass up to 2.5 GeV/c² is studied using proton-proton collision data recorded at centre-of-mass energies of 7, 8, and 13 TeV collected with the LHCb detector, corresponding to a total integrated luminosity of 9 fb⁻¹. Results are given in terms of fit and interference fractions between the different components contributing to this final state. Only Λ resonances decaying to pK⁻ are found to be relevant, where the largest contributions stem from the Λ(1520), Λ(1600), Λ(1800), and Λ(1890) states.
