The thermal heat kernel expansion and the one-loop effective action of QCD at finite temperature
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The heat kernel expansion for field theory at finite temperature is constructed. It is based on the imaginary time formalism and applies to generic Klein-Gordon operators in flat s…
The Spectral Quark Model and Light Cone Phenomenology
E. Ruiz Arriola, Wojciech Broniowski
Chiral quark models offer a practical and simple tool to describe covariantly both low and high energy phenomenology in combination with QCD evolution. This can be done in full har…
Impact-Parameter Dependence of the Diagonal GPD of the Pion from Chiral Quark Models
Wojciech Broniowski, Enrique Ruiz Arriola
We analyze the impact-parameter dependent diagonal non-singlet generalized parton distribution of the pion in two distinct chiral quark models: the Spectral Quark Model and the Nam…
Impact-parameter dependence of the generalized parton distribution of the pion in chiral quark models
Wojciech Broniowski, Enrique Ruiz Arriola
We compute the off-forward diagonal non-singlet generalized parton distribution of the pion in two distinct chiral quark models: the Nambu-Jona-Lasinio model with the Pauli-Villars…
Spectral quark model and low-energy hadron phenomenology
Enrique Ruiz Arriola, Wojciech Broniowski
We propose a spectral quark model which can be applied to low energy hadronic physics. The approach is based on a generalization of the Lehmann representation of the quark propagat…
