The resonant structure of the radiative decay Lambdab0-> pK-gamma 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 Lambda resonances decaying to pK- are found to be relevant, where the largest contributions stem from the Lambda(1520), Lambda(1600), Lambda(1800), and Lambda(1890) states.

Abstract
The resonant structure of the radiative decay Lambdab0-> pK-gamma 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 Lambda resonances decaying to pK- are found to be relevant, where the largest contributions stem from the Lambda(1520), Lambda(1600), Lambda(1800), and Lambda(1890) states.| File | Dimensione | Formato | |
