Parton Distributions Functions of Pion, Kaon and Eta pseudoscalar mesons in the NJL model
R. M. Davidson, E. Ruiz Arriola
Parton distributions of pseudoscalar pi,K and eta mesons obtained within the NJL model using the Pauli-Villars regularization method are analyzed in terms of LO and NLO evolution,…
The Inverse Amplitude Method in Scattering in Chiral Perturbation Theory to Two Loops
J. Nieves, M. Pavon Valderrama, E. Ruiz Arriola
The inverse amplitude method is used to unitarize the two loop scattering amplitudes of SU(2) Chiral Perturbation Theory in the , and channels. An…
Parton distributions for the pion in a chiral quark model
E. Ruiz Arriola
Parton distributions for the pion are studied in a chiral quark model characterized by a quark propagator for which a spectral representation is assumed. Electromagnetic and chiral…
The (1535) and (1650) Resonances in Meson-Baryon Unitarized Coupled Channel Chiral Perturbation Theory
Juan Nieves, Enrique Ruiz Arriola
The wave meson-baryon scattering is analyzed for the strangeness S=0 sector in a Bethe-Salpeter coupled channel formalism incorporating Chiral Symmetry. Four channels have been…
