Title: Baryon Regge Trajectories in the Light of the 1/Nc Expansion

Journal Article · · Phys.Lett.B

We analyze Regge trajectories in term the $$1/N_c$$ expansion of QCD. Neglecting spin-orbit contributions to the large $$N_c$$ baryon mass operator, we consider the evolution of the spin-flavor singlet component of the masses with respect $$\ell$$. We find two distinct and remarkably linear Regge trajectories for symmetric and for mixed symmetric spin-flavor multiplets.
