Amplitude analysis of the Λb0→pK−γ decay

Aaij, R. ; Ruiz-Vidal, Joan LU and Zunica, G. (2024) In Journal of High Energy Physics 2024(6).
Abstract
The resonant structure of the radiative decay Λb0→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. © The Author(s) 2024.
