Scenario for quark confinement from infrared safe Yang-Mills dynamics
Marcela Peláez, Urko Reinosa, Julien Serreau +2
We revisit the non-Abelian dipole problem in the context of a simple semiclassical approach that incorporates some essential features of the infrared sector of Yang-Mills theories…
Center-symmetric Landau gauge: Further signatures of confinement
Duifje Maria van Egmond, Urko Reinosa
In a recent article [1], we have identified new signatures for the Yang-Mills deconfinement transition, based on the finite-temperature longitudinal or (chromo-)electric gluon prop…
Gauge fixing and physical symmetries
Duifje Maria van Egmond, Urko Reinosa
We analyze how gauge fixing, which is required by any practical continuum approach to gauge systems, can interfere with the physical symmetries of such systems. In principle, the g…
Polyakov loop, gluon mass, gluon condensate and its asymmetry near deconfinement
D. Dudal, D. M. van Egmond, U. Reinosa +1
We consider a BRST invariant generalization of the "massive background Landau gauge", resembling the original Curci-Ferrari model that saw a revived interest due to its phenomenolo…
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…
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…
Perturbative aspects of the deconfinement transition -- Physics beyond the Faddeev-Popov model
Urko Reinosa
In the case of non-abelian gauge theories, the standard Faddeev-Popov (FP) gauge-fixing procedure in the Landau gauge is known to be incomplete due to the presence of gauge-equival…
The ghost-antighost-gluon vertex from the Curci-Ferrari model: Two-loop corrections
Nahuel Barrios, Marcela Peláez, Urko Reinosa +1
The Curci-Ferrari model has been shown to provide a good grasp on pure Yang-Mills correlation functions in the Landau gauge, already at one-loop order. In a recent work, the robust…
The scalar sunset diagram at finite temperature with imaginary square masses
Duifje Maria van Egmond, Urko Reinosa
We evaluate the finite temperature scalar sunset diagram with imaginary square masses, that appears in the Gribov-Zwanziger approach to Yang-Mills (YM) theory beyond one-loop order…
Symmetry restoration and the gluon mass in the Landau gauge
Camille Noûs, Urko Reinosa, Julien Serreau +2
We investigate the generation of a gluon screening mass in Yang-Mills theory in the Landau gauge. We propose a gauge-fixing procedure where the Gribov ambiguity is overcome by summ…
Two loop calculation of Yang-Mills propagators in the Curci-Ferrari model
John A. Gracey, Marcela Peláez, Urko Reinosa +1
The Landau-gauge gluon and ghost correlation functions obtained in lattice simulations can be reproduced qualitatively and, to a certain extent, quantitatively if a gluon mass is a…
Localized rainbows in the QCD phase diagram
Jan Maelger, Urko Reinosa, Julien Serreau
We study the phase diagram of strongly interacting matter with light quarks using a recently proposed, small parameter approach to infrared QCD in the Landau gauge. This is based o…
Universal aspects of the phase diagram of QCD with heavy quarks
Jan Maelger, Urko Reinosa, Julien Serreau
The flavor dependence of the QCD phase diagram presents universal properties in the heavy quark limit. For the wide class of models where the quarks are treated at the one-loop lev…
A Gribov-Zwanziger type action invariant under background gauge transformations
Daniel Kroff, Urko Reinosa
We propose a Gribov-Zwanziger type action for the Landau-DeWitt gauge that preserves, for any gauge group, the invariance under background gauge transformations. At zero temperatur…
Small parameters in infrared quantum chromodynamics
Marcela Peláez, Urko Reinosa, Julien Serreau +2
We study the long-distance properties of quantum chromodynamics in an expansion in powers of the three-gluon, four-gluon, and ghost-gluon couplings, but without expanding in the qu…
How nonperturbative is the infrared regime of Landau gauge Yang-Mills correlators?
Urko Reinosa, Julien Serreau, Matthieu Tissier +1
We study the Landau gauge correlators of Yang-Mills fields for infrared Euclidean momenta in the context of a massive extension of the Faddeev-Popov Lagrangian which, we argue, und…
A perturbative approach to the confinement-deconfinement phase transition
Urko Reinosa
We summarize recent progress in describing the confinement-deconfinement transition from a novel perturbative approach.
Yang-Mills correlators across the deconfinement phase transition
U. Reinosa, J. Serreau, M. Tissier +1
We compute the finite temperature ghost and gluon propagators of Yang-Mills theory in the Landau-DeWitt gauge. The background field that enters the definition of the latter is inti…
Perturbative study of the QCD phase diagram for heavy quarks at nonzero chemical potential
Urko Reinosa, Julien Serreau, Matthieu Tissier
We investigate the phase diagram of QCD with heavy quarks at finite temperature and chemical potential in the context of background field methods. In particular, we use a massive e…
Deconfinement transition in SU(2) Yang-Mills theory: A two-loop study
U. Reinosa, J. Serreau, M. Tissier +1
In a recent work we have proposed a perturbative approach for the study of the phase transition of pure Yang-Mills theories at finite temperature. This is based on a simple massive…
Yang-Mills correlators at finite temperature: A perturbative perspective
U. Reinosa, J. Serreau, M. Tissier +1
We consider the two-point correlators of Yang-Mills theories at finite temperature in the Landau gauge. We employ a model for the corresponding Yang-Mills correlators based on the…
