The Polyakov loop and the heat kernel expansion at finite temperature
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The lower order terms of the heat kernel expansion at coincident points are computed in the context of finite temperature quantum field theory for flat space-time and in the presen…
Meson-Baryon Interactions in Unitarized Chiral Perturbation Theory
C. Garcia-Recio, J. Nieves, E. Ruiz Arriola +1
Meson-Baryon Interactions can be successfully described using both Chiral Symmetry and Unitarity. The wave meson-baryon scattering amplitude is analyzed in a Bethe-Salpeter cou…
Meson-Baryon Unitarized Coupled Channel Chiral Perturbation Theory and the (1405) and (1670) Resonances
C. Garcia-Recio, J. Nieves, E. Ruiz Arriola +1
The wave meson-baryon scattering is analyzed for the strangeness and isospin I=0 sector in a Bethe-Salpeter coupled channel formalism incorporating Chiral Symmetry. Four…
Pion Structure at High and Low Energies in Chiral Quark Models
E. Ruiz Arriola
Low and high energy properties of the pion are reviewed in the framework of chiral quark models. Particular emphasis is put on the simplest version of the SU(2) NJL model as protot…
S=--1 Meson-Baryon Scattering in Coupled Channel Unitarized Chiral Perturbation Theory
C. Garcia-Recio, J. Nieves, E. Ruiz Arriola +1
The wave meson-baryon scattering amplitude is analyzed for the strangeness and isospin I=0 sector in a Bethe-Salpeter coupled channel formalism incorporating Chiral Symm…
Pion light-cone wave function and pion distribution amplitude in the Nambu-Jona-Lasinio model
Enrique Ruiz Arriola, Wojciech Broniowski
We compute the pion light-cone wave function and the pion quark distribution amplitude in the Nambu-Jona-Lasinio model. We use the Pauli-Villars regularization method and as a resu…
