Polyakov loop in chiral quark models at finite temperature
E. Megias, E. Ruiz Arriola, L. L. Salcedo
We describe how the inclusion of the gluonic Polyakov loop incorporates large gauge invariance and drastically modifies finite temperature calculations in chiral quark models after…
Chiral Lagrangians at finite temperature and the Polyakov Loop
E. Megias, E. Ruiz Arriola, L. L. Salcedo
Heat kernel expansions at finite temperature of massless QCD and chiral quark models generate effective actions relevant for both low and high temperature QCD. The key relevance of…
Singlet NN Regularization using a Boundary Condition for OPE and TPE potentials
M. Pavon Valderrama, E. Ruiz Arriola
Boundary conditions provide a simple and physically compelling Wilsonian renormalization method in coordinate space in the framework of effective field theory as applied to nucleon…
Polyakov Loop at Finite Temperature in Chiral Quark Models
E. Megias, E. Ruiz Arriola, L. L. Salcedo
At finite temperature, chiral quark models do not incorporate large gauge invariance which implies genuinely non-perturbative finite temperature gluonic degrees of freedom. Motivat…
Application of chiral quark models to high-energy processes
Wojciech Broniowski, Enrique Ruiz Arriola
We discuss the predictions of chiral quark models for basic pion properties entering high-energy processes: generalized parton distributions (GPD's) and unintegrated parton distrib…
Landau-gauge condensates from the quark propagator on the lattice
Enrique Ruiz Arriola, Patrick Oswald Bowman, Wojciech Broniowski
We compute the dimension-2 condensate, <A^2>, and the dimension-4 mixed condensate, <\bar q A q>, from the recent quenched lattice results for the quark propagator in the Landau ga…
