Query: Many-quark interactions: Large-$N$ scaling and contribution to baryon
  masses   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.
