Symmetry restoration and the gluon mass in the Landau gauge

Autor: Urko Reinosa, Julien Serreau, Rodrigo Carmo Terin, Matthieu Tissier

Publikováno v: SciPost Physics, Vol 10, Iss 2, p 035 (2021)

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 summing over all Gribov copies with some weight function. This can be f

A novel background field approach to the confinement-deconfinement transition

Autor: Duifje Maria van Egmond, Urko Reinosa, Julien Serreau, Matthieu Tissier

Publikováno v: SciPost Physics, Vol 12, Iss 3, p 087 (2022)

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 generalisation of the Landau gauge (to which it reduces at vanishi

Phys.Rev.D, 2023, 107 (5), pp.054025. ⟨10.1103/PhysRevD.107.054025⟩

We continue our investigation of the QCD dynamics in terms of the Curci-Ferrari effective Lagrangian, a deformation of the Faddeev-Popov one in the Landau gauge with a tree-level gluon mass term. In a previous work we have studied the dynamics of chi

Two-loop three-gluon vertex from the Curci-Ferrari model and its leading infrared behavior to all loop orders

Autor: Nahuel Barrios, Marcela Peláez, Urko Reinosa

Publikováno v: Physical Review

We evaluate the three-gluon vertex with one vanishing external momentum within the Curci-Ferrari (CF) model at two-loop order and compare our results to Landau-gauge lattice simulations of the same vertex function for the SU(2) and SU(3) gauge groups

Signatures of the Yang-Mills deconfinement transition from the gluon two-point correlator

Autor: Duifje Maria van Egmond, Urko Reinosa

Publikováno v: Physical Review

We evaluate the longitudinal or (chromo-)electric Yang-Mills gluon propagator in the recently proposed center-symmetric Landau gauge at finite temperature [1]. To model the effect of the Gribov copies in the infrared, we use the Curci-Ferrari model w
