“…It is more convenient to represent this infinite tower of baryon states by a collective coordinate A from which the I = J baryons can be obtained by projection [10] [12]. Since the baryon mass splittings are order 1/N c [4], the collective coordinate A does not evolve with time at leading order in 1/N c .…”

The large-N c limit of the meson-baryon effective Lagrangian is shown to reduce to a semiclassical field theory. A chiral bag structure emerges naturally in the N c → ∞ limit.A possible connection between the chiral bag picture and the Skyrme model is discussed.The classical meson-baryon theory is used to reproduce the M 3 π non-analytic correction to the baryon mass obtained previously as a loop correction in chiral perturbation theory.

“…(2) In the algebraic method, Skyrme model results have been interpreted to be the limit of N c → ∞ [11,12]. Specifically, this has been explicitly shown using the so called quark representation, the symmetric representation with Young tableau [N c ] of the SU(4) group generated by spin and isospin.…”

The large-N c limit and the behavior of g (0)A and g A Atsushi Hosaka (1) and Niels R. Walet (2) (1) Numazu College of Technology, 3600 Ooka, Numazu, Shizuoka, 410 Japan We investigate the isoscalar and isovector components of the axial vector coupling constants, g (0)A and g A using algebraic models that lead to the correct symmetries of large-N c QCD. Results obtained previously in various chiral models are interpreted from this algebraic point of view. The results of the Skyrme model and the valence quark model are explained by simple realizations of the algebra.

We examine SU(3) constraints on the spectrum and decay widths of cryptoexotic nucleon-like states in antidecuplet of pentaquarks. We show that in the ideal mixing scenario the number of free matrix elements describing splittings reduces from 4 to 2. Model-independent sum rules are derived. Using as input $\Theta^+$ and $\Xi_{3/2}$ masses we show that it is difficult to interpret Roper and $N^{\ast}(1710)$ nucleon resonances as cryptoexotic pentaquarks. Large $N_c$ limit for antidecuplet and accompanying octet in the diqaurk picture and the analogy with the soliton model is also discussed.Comment: 9 pages, 5 figures, contribution to Festschrift for Klaus Goeke's 60th birthday, to be published in Nov./Dec. 2004 issue of Annalen der Physi
