Gravitational, electromagnetic, and transition form factors of the pion
Wojciech Broniowski, Enrique Ruiz Arriola
Results of the Spectral Quark Model for the gravitational, electromagnetic, and transition form factors of the pion are discussed. In this model both the parton distribution amplit…
Renormalization and Universality of NN interactions in Chiral Quark and Soliton Models
E. Ruiz Arriola, A. Calle Cordon
We use renormalization as a tool to extract universal features of the NN interaction in quark and soliton nucleon models, having the same long distance behaviour but different shor…
Application of chiral quarks to high-energy processes and lattice QCD
Wojciech Broniowski, Enrique Ruiz Arriola
Results of the chiral quark models for the soft matrix elements involving pions and photons, relevant for high-energy processes, are reviewed. We discuss quantities related to the…
Photon interactions and chiral dynamics
Wojciech Broniowski, Alexandr E. Dorokhov, Enrique Ruiz Arriola
Twist-2 components of the real and virtual photon distribution amplitudes are evaluated in several chiral quark models. The results, obtained at the quark model scale, are then evo…
Meson Resonances at large Nc: Complex Poles vs Breit-Wigner Masses
J. Nieves, E. Ruiz Arriola
The rigorous quantum mechanical definition of a resonance requires determining the pole position in the second Riemann sheet of the analytically continued partial wave scattering a…
Properties of the rho and sigma Mesons from Unitary Chiral Dynamics
J. Nieves, E. Ruiz Arriola
The chiral limit of the rho and sigma masses and widths is discussed. We work within the inverse amplitude method to one loop in SU(2) ChPT and analyze the consequences that all ch…
