Collaboration
Marcela Peláez is based at the Universidad de la República, Montevideo, Uruguay. The collaboration began in 2022. One joint paper has been published so far: Phys. Rev. D 109 (2024), focused on the ghost-gluon vertex at general kinematics in the refined Gribov-Zwanziger (RGZ) theory. This makes her the group’s primary international collaborator in Uruguay.
Joint Work
- Ghost-gluon vertex at general kinematics in RGZ theory (Phys. Rev. D 109, 2024): the single joint publication to date. The paper studies the ghost-gluon vertex beyond the Taylor kinematics limit within the RGZ framework, connecting the Gribov-horizon-modified propagators to the vertex structure that governs the running coupling in Landau gauge. This work builds on the Gribov-Zwanziger and RGZ actions developed in the longer-standing joint work with leticia-palhares and silvio-paolo-sorella.
