Charm and bottom baryon masses in the combined 1/Nc and 1/mQ expansion versus the quark model

[en] A good agreement between a flux tube-based quark model of light baryons (strange and nonstrange) and the 1/Nc expansion mass formula has been found in previous studies. In the present work a larger connection is established between the quark model and the 1/Nc and 1/mQ expansion method by extending the previous procedure to baryons made of one heavy and two light quarks. The compatibility between both approaches is shown to hold in this sector too.
