Nonrelativistic meson masses from the Curci-Ferrari model
Anaclara Alvez, Nahuel Barrios, Florencia Benítez +1
We study the mass spectrum of nonrelativistic mesons composed of charm and bottom quarks within the framework of the Curci-Ferrari model in the Landau gauge, focusing on the influe…
Four-gluon vertex from the Curci-Ferrari model at one-loop order
Nahuel Barrios, Philipe De Fabritiis, Marcela Peláez
We compute the four-gluon vertex from the Curci-Ferrari model at one-loop order for a collinear configuration. Our results display a good agreement with the first lattice data for…
Ghost-gluon vertex in the presence of the Gribov horizon: General kinematics
Nahuel Barrios, Marcelo S. Guimaraes, Bruno W. Mintz +2
Correlation functions are important probes for the behavior of quantum field theories. Already at tree-level, the Refined Gribov Zwanziger (RGZ) effective action for Yang-Mills the…
Two-loop three-gluon vertex from the Curci-Ferrari model and its leading infrared behavior to all loop orders
Nahuel Barrios, Marcela Peláez, Urko Reinosa
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 simula…
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…
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…
Stress energy tensor renormalization for a spherically symmetric massive scalar field on a quantum space-time
Nahuel Barrios, Rodolfo Gambini, Jorge Pullin
We consider a massive scalar field living on the recently found exact quantum space-time corresponding to vacuum spherically symmetric loop quantum gravity. The discreteness of the…
