Transversity structure of the pion in chiral quark models
Wojciech Broniowski, Enrique Ruiz Arriola, Alexander E. Dorokhov
We describe the chiral quark model evaluation of the transversity Generalized Parton Distributions (tGPDs) and related transversity form factors (tFFs) of the pion. The obtained tG…
0++ states in a large-Nc Regge approach
Enrique Ruiz Arriola, Wojciech Broniowski
Scalar-isoscalar states () are discussed within the large- Regge approach. We find that the lightest scalar-isoscalar state fits very well into the p…
Transversity Form Factors and Generalized Parton Distributions of the pion in chiral quark models
Wojciech Broniowski, Alexander E. Dorokhov, Enrique Ruiz Arriola
The transversity Generalized Parton Distributions (tGPDs) and related transversity form factors of the pion are evaluated in chiral quark models, both local (Nambu--Jona-Lasinio) a…
Renormalization approach to constituent quark models of Quarkonium
J. Segovia, D. R. Entem, F. Fernandez +1
Constituent quark models, while successful, require a great deal of fine tuning of the short distance interactions by introducing phenomenological gluonic form factors which are ul…
Generalized Quark Transversity Distribution of the Pion in Chiral Quark Models
Alexander E. Dorokhov, Wojciech Broniowski, Enrique Ruiz Arriola
The transversity generalized parton distributions (tGPDs) of the the pion, involving matrix elements of the tensor bilocal quark current, are analyzed in chiral quark models. We ap…
Large-Nc Properties of the rho and f0(600) Mesons from Unitary Resonance Chiral Dynamics
J. Nieves, A. Pich, E. Ruiz Arriola
We construct pi-pi amplitudes that fulfill exact elastic unitarity, account for one loop Chiral Perturbation Theory contributions and include all 1/Nc leading terms, with the only…
