A window on infrared QCD with small expansion parameters
Marcela Peláez, Urko Reinosa, Julien Serreau +2
Lattice simulations of the QCD correlation functions in the Landau gauge have established two remarkable facts. First, the coupling constant in the gauge sector remains finite and…
SU() Cartan-Weyl bases and color factors
Duifje Maria van Egmond, Urko Reinosa
Constant temporal backgrounds have become a convenient tool for the discussion of continuum non-abelian gauge theories at finite temperature, as they provide a grasp on the confine…
A novel background field approach to the confinement-deconfinement transition
Duifje Maria van Egmond, Urko Reinosa, Julien Serreau +1
We propose a novel approach to the confinement-deconfinement transition in Yang-Mills theories in the context of gauge-fixed calculations. The method is based on a background-field…
On overlapping Feynman (sub)graphs
Urko Reinosa
We discuss, on general grounds, how two subgraphs of a given Feynman graph can overlap with each other. For this, we use the notion of connecting and returning lines that describe…
Two-loop corrections to the QCD propagators within the Curci-Ferrari model
Nahuel Barrios, John A. Gracey, Marcela Peláez and +1
We evaluate all two-point correlation functions of the Curci-Ferrari (CF) model in four dimensions and in the presence of mass-degenerate fundamental quark flavors, as a natural ex…
Functional renormalization group and 2PI effective action formalism
Jean-Paul Blaizot, Jan M. Pawlowski, Urko Reinosa
We combine two non-perturbative approaches, one based on the two-particle-irreducible (2PI) action, the other on the functional renormalization group (fRG), in an effort to develop…
