Title Baryon Effective Theories and Phenomenology in the 1/Nc Expansion
Abstract Chiral perturbation theory (ChPT) and the 1/Nc expansion provide systematic frameworks to investigate the strong interaction at low energy. There are two main focuses of this dissertation. First, analyzing the masses of baryons in the framework of the 1/Nc expansion, using the available physical masses and masses calculated in lattice QCD. Second, combining both ChPT and the 1/Nc expansion into a single framework and applying it to the phenomenology of baryons with three light-quark ¿avors. In the first focus, the baryon states are organized into irreducible representations of SU(6)×O(3), where the [56,lP = 0+] contains the ground state and radially excited baryons, and the [56,2^+] and [70,1^-] contain orbitally excited states are analyzed. The analyses are carried out to O(1/Nc) and first order in the quark masses. The issue of state identifications is discussed. Numerous parameter independent mass relations and the famous Gell-Mann-Okubo (GMO) and Equal-Spacing (ES) relations
