# Faddeev study of heavy-baryon spectroscopy

@article{Garcilazo2007FaddeevSO, title={Faddeev study of heavy-baryon spectroscopy}, author={Humberto Garcilazo and Javier Vijande and Alfredo Valcarce}, journal={Journal of Physics G}, year={2007}, volume={34}, pages={961-976} }

We investigate the structure of heavy baryons containing a charm or a bottom quark. We employ a constituent quark model successful in the description of the baryon–baryon interaction which is consistent with the light-baryon spectra. We solve exactly the three-quark problem by means of the Faddeev method in momentum space. Heavy-baryon spectrum shows a manifest compromise between perturbative and nonperturbative contributions. The flavour dependence of the one-gluon exchange is analysed. We… Expand
