Large N Weinberg - Tomozawa interaction and spin - flavor symmetry
نویسندگان
چکیده
The construction of an extended version of the Weinberg-Tomozawa Lagrangian, in which baryons and mesons form spin-flavor multiplets, is reviewed and some of its properties discussed, for an arbitrary number of colors and flavors. The coefficient tables of spin-flavor irreducible representations related by crossing between the s-, t-and u-channels are explicitly constructed.

Resonances and the Weinberg – Tomozawa 56 - baryon – 35 - meson interaction
Resonances and the Weinberg–Tomozawa 56-baryon –35-meson interaction. Abstract. Vector meson degrees of freedom are incorporated into the Weinberg-Tomozawa (WT) meson-baryon chiral Lagrangian by using a scheme which relies on spin–flavor SU(6) symmetry. The corresponding Bethe-Salpeter approximation successfully reproduces previous SU(3)–flavor WT results for the lowest-lying s–wave negative pa...
متن کاملLight Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD
The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large N limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion coupling constant for light quark baryons. Light quark symmetry relations amongst the baryon couplings are violated at order 1/N. Heavy quark spin-fla...
متن کاملStudy of exotic hadrons in S-wave scatterings induced by chiral interaction in the flavor symmetric limit
We study s-wave bound states of a hadron and a light pseudoscalar meson induced by the Weinberg-Tomozawa (WT) interaction in the flavor SU(3) symmetric limit. The WT interaction is a driving force to generate quasibound states dynamically in the chiral unitary approaches. The strength and sign of the WT interaction are determined only by the group theoretical structure of the target hadrons, an...
متن کاملCharm and bottom baryon masses in the 1/N expansion
The 1/Nc expansion has proven useful for studying the spin-flavor properties of baryons containing light quarks. A spin-flavor symmetry for baryons is defined in large-Nc QCD. Away from the Nc → ∞ limit, 1/Nc corrections which break large-Nc baryon spin-flavor symmetry can be classified in terms of the spin and flavor symmetries which remain for finite Nc. Since explicit SU(3) flavor symmetry b...
متن کاملThe Spin-Flavor Dependence of Nuclear Forces From Large-N QCD
We show that nuclear interactions are SU(4) symmetric at leading order in chiral perturbation theory in the large-N limit of QCD. The nucleons and delta resonances form a 20-dimensional representation of SU(4) and we show how Wigner’s supermultiplet symmetry SU(4)sm, under which the nucleons transform as a 4-dimensional representation, follows as an accidental low energy symmetry. Exploiting SU...
