Starting from an effective Hamiltonian modelling a baryon made of N identical quarks in the large-N approach of QCD, we obtain analytical formulas allowing to estimate the contributions of multiquark interactions to the baryon mass. The cases of vanishing (mass spectrum) and non-vanishing (baryon melting) temperatures are treated.
