Landau-Khalatnikov-Fradkin transformations for the two loop massless quark propagator

Autor: Dall'Olio, Pietro, De Meerleer, Tim, Dudal, David, Sorella, Silvio Paolo, Bashir, Adnan

Landau-Khalatnikov-Fradkin transformations (LKFTs) yield the gauge dependence of correlation functions within the class of linear covariant gauges. We derive the LKFT for the quark propagator and explicitly evaluate it up to the two loop level in the

Homotopy data as part of the lattice field: A first study

Autor: Dall'Olio, Pietro, Zapata, José A.

Fields exhibit a variety of topological properties, like different topological charges, when field space in the continuum is composed by more than one topological sector. Lattice treatments usually encounter difficulties describing those properties.

Exploiting the scheme dependence of the renormalization group improvement in infrared Yang-Mills theory

Autor: Dall'Olio, Pietro, Weber, Axel

Within the refined Gribov-Zwanziger scenario for four-dimensional Yang-Mills theory in the Landau gauge, a gluon mass term is generated from the restriction of the gauge field configurations to the first Gribov region. Tissier and Wschebor have point

Landau-Khalatnikov-Fradkin Transformations, Nielsen Identities, Their Equivalence and Implications for QCD

Autor: De Meerleer, Tim, Dudal, David, Sorella, Silvio Paolo, Dall'Olio, Pietro, Bashir, Adnan

Publikováno v: Phys. Rev. D 101, 085005 (2020)

The Landau-Khalatnikov-Fradkin transformations (LKFTs) represent an important tool for probing the gauge dependence of the correlation functions within the class of linear covariant gauges. Recently these transformations have been derived from first
