Renormalization of Singular Potentials and Power Counting
M. Pavon Valderrama, E. Ruiz Arriola
We analyze the renormalization of the nucleon--nucleon interaction at low energies in coordinate space for both one and two pion exchange chiral potentials. The singularity structu…
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 Expansion, Renormalization and the Nuclear Force
E. Ruiz Arriola, M. Pavon Valderrama
The renormalization of singular chiral potentials as applied to NN scattering and the structure of the deuteron is discussed. It is shown how zero range theories may be implemented…
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…
