Descrição: Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2022, Tutora: Àngels Ramos Gómez We follow on the steps of the LHCb collaboration which first discovered five excited states of baryons with strangeness and charm, Ωc0, in pp collisions, by discussing the Ω− →πΞc+K−decay, a process which has been recently studied by the same collaboration obtaining four narrow Ωc0 states compatible with the previously found ones. We explore these new found states from a hadronic molecular viewpoint and find that two out of the four resonances, Ωc(3050)0 and Ωc(3090)0, might be interpreted as pentaquark states, structured as meson-baryon bound molecules.
