چکیده

Low-energy sum rules and large-Nc consistency conditions
The large-Nc consistency conditions for axial vector and isovector magnetic couplings of pions to baryons are discussed from the point of view of lowenergy current-algebra sum rules (Adler-Weisberger, Cabibbo-Radicati). In particular, we show how the result that ratios of axial vector and isovector magnetic coupling constants get corrections only at the order 1/N2 c follows from the Nc-counting...
متن کاملExpansion in Chiral Quark Model of Mesons
We study SU(3)L×SU(3)R chiral quark model of mesons up to the next to leading order of 1/Nc expansion. Composite vector and axial-vector mesons resonances are introduced via non-linear realization of chiral SU(3) and vector meson dominant. Effects of one-loop graphs of pseudoscalar, vector and axial-vector mesons is calculated systematically and the significant results are obtained. We also inv...

The fermion and meson sectors of the quark-level SU(2) linear sigma model are dynamically generated from a meson-quark Lagrangian, with the quark (q) and meson (σ, π) fields all treated as elementary, having neither bare masses nor expectation values. In the chiral limit, the masses are predicted to be mq = fπg, mπ = 0, mσ = 2mq, and we also find that the quark-meson coupling is g = 2π/ √ Nc, t...
متن کاملChiral properties of the constituent quark model
We show that, in a model based exclusively on constituent-quark degrees of freedom interacting via a potential, the full axial current is conserved if the spectrum of Q̄Q states contains a massless pseudoscalar. The current conservation emerges nonperturbatively if the model satisfies certain constraints on (i) the axial coupling gA of the constituent quark and (ii) the Q̄Q potential at large dis...

We calculate the axial form factor in the chiral quark soliton (semibosonized Nambu Jona-Lasinio) model using the semiclassical quantization scheme in the next to leading order in angular velocity. The obtained axial form factor is in a good absolute (without additional scaling) agreement with the experimental data. Both the value at the origin and the q-dependence of the form factor as well as...
