Njl Model on the Light Cone and Pion Structure Function *
The NJL model is formulated on the light cone. Using the 1/N expansion to solve the fermionic constraint, an effective 4-fermi la-grangian is derived. Pionic properties are investigated using this la-grangian, and the formal equivalence to the equal-time formulation is demonstrated. Two regularization schemes in terms of light-cone variables are discussed: An extension of the 'invariant mass cu...
متن کاملPion Properties in the 1 / N c - corrected NJL model
We investigate the effect of mesonic fluctuations on the pion propagator in the Nambu–Jona-Lasinio (NJL) model by explicitly taking into account 1/N c-corrections. Because of the non-renormalizability of the model we have to regularize the meson loops with an independent cutoff parameter Λ M. Whereas for moderate values of Λ M the properties of the pion change only quantitatively we encounter s...
متن کاملParton Distributions Functions of Pion, Kaon and Eta pseudoscalar mesons in the NJL model
Parton distributions of pseudoscalar π,K and η mesons obtained within the NJL model using the Pauli-Villars regularization method are analyzed in terms of LO and NLO evolution, and the valence sea quark and gluon parton distributions for the pion are obtained at Q2 = 4GeV and compared to existing parametrizations at that scale. Surprisingly, the NLO order effects turn out to be small compared t...
متن کاملNJL - model ∗
The Nambu-Jona-Lasinio model is supplemented by the quark interaction generated by the one-gluon exchange. The employed gluon propagator exhibits the correct large momentum behavior of QCD, whereas the Landau-pole at low energies is screened. The emerging constituent quark model is one-loop renormalizable and interpolates between the phenomenologically successful Nambu-Jona-Lasinio model at low...
متن کاملElectromagnetic Pion Form Factor and Neutral Pion Decay Width
The electromagnetic pion form factor, Fπ(q 2), is calculated for spacelike-q2 in impulse approximation using a confining quark propagator, S, and a dressed quarkphoton vertex, Γμ, obtained from realistic, nonperturbative Dyson-Schwinger equation studies. Good agreement with the available data is obtained for Fπ(q 2) and other pion observables, including the decay π0 → γ γ. This calculation sugg...
