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…
From chiral quark models to high-energy processes
Wojciech Broniowski, Enrique Ruiz Arriola
We show the results of low-energy chiral quark models for soft matrix elements involving pions and photons. Such soft elements, upon convolution with the hard matrix elements, are…
Trace Anomaly, Thermal Power Corrections and Dimension Two condensates in the deconfined phase
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The trace anomaly of gluodynamics on the lattice shows clear fingerprints of a dimension two condensate above the phase transition. The condensate manifests itself through even pow…
