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…
Nonrelativistic meson masses from the Curci-Ferrari model
Anaclara Alvez, Nahuel Barrios, Florencia BenÃtez +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…
The infrared-safe Minkowskian Curci-Ferrari model
Santiago Oribe, Marcela Peláez, Urko Reinosa
We discuss the existence of Landau-pole-free renormalization group trajectories in the Minkowskian version of the Curci-Ferrari model as a function of a running parameter ass…
Unitarization of the one-loop graviton-graviton scattering amplitudes and study of the graviball
J. A. Oller, Marcela Peláez
From the graviton-graviton scattering amplitudes calculated perturbatively in quantum gravity to the one-loop order, we develop further a formalism that allows one to calculate inf…
Unitarization of electron scattering with an external potential at NLO in QED
J. A. Oller, Marcela Peláez
We have calculated the one-loop scattering amplitude of an electron by an external Coulomb potential in QED free of infrared divergences. This feature is achieved by applying the F…
