The Quantum and Local Polyakov loop in Chiral Quark Models at Finite Temperature
E. Megias, E. Ruiz Arriola, L. L. Salcedo
We describe results for the confinement-deconfinement phase transition as predicted by the Nambu--Jona-Lasinio model where the local and quantum Polyakov loop is coupled to the con…
Confined Chiral Solitons in the Spectral Quark Model
Enrique Ruiz Arriola, Wojciech Broniowski, Bojan Golli
Chiral solitons with baryon number one are investigated in the Spectral Quark Model. In this model the quark propagator is a superposition of complex-mass propagators weighted with…
Chiral Lagrangian at finite temperature from the Polyakov-Chiral Quark Model
E. Megias, E. Ruiz Arriola, L. L. Salcedo
We analyze the consequences of the inclusion of the gluonic Polyakov loop in chiral quark models at finite temperature. Specifically, the low-energy effective chiral Lagrangian fro…
Photon distribution amplitudes and light-cone wave functions in chiral quark models
A. E. Dorokhov, W. Broniowski, E. Ruiz Arriola
The leading- and higher-twist distribution amplitudes and light-cone wave functions of real and virtual photons are analyzed in chiral quark models. The calculations are performed…
Pion transition form factor and distribution amplitudes in large-Nc Regge models
Enrique Ruiz Arriola, Wojciech Broniowski
We analyze the pi -> gamma* gamma* amplitude in the framework of radial Regge models in the large-Nc limit. With the assumption of similarity of the asymptotic Regge rho and omega…
Dimension-two gluon condensate from large-Nc Regge models
Enrique Ruiz Arriola, Wojciech Broniowski
It is shown that in the large-N_c limit radial Regge trajectories give rise in a natural way to the presence of the dimension-2 gluon condensate, <A^2>, in meson correlators. We ma…
