Lepton number violation at hadron colliders via pseudo-Dirac heavy neutral leptons
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
Symmetry-protected low-scale seesaw models can account for the observed neutrino flavour oscillations without fine-tuning, while yielding collider-accessible signatures through pse…
Infrared properties of the quark-gluon vertex in general kinematics
A. C. Aguilar, M. N. Ferreira, G. T. Linhares +2
In the present work we determine the eight form factors of the transversely-projected quark-gluon vertex in general kinematics, in the context of Landau-gauge QCD with two degenera…
Discovering heavy neutrino-antineutrino oscillations at the -pole
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
Collider-testable type I seesaw extensions of the Standard Model are generally protected by an approximate lepton number (LN) symmetry. Consequently, they predict pseudo-Dirac heav…
Heavy neutrino-antineutrino oscillations at the FCC-ee
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
We discuss the impact of heavy neutrino-antineutrino oscillations (NNOs) on heavy neutral lepton (HNL) searches at proposed electron-positron colliders such as the future circular…
Schwinger poles of the three-gluon vertex: symmetry and dynamics
A. C. Aguilar, M. N. Ferreira, B. M. Oliveira +2
The implementation of the Schwinger mechanism endows gluons with a nonperturbative mass through the formation of special massless poles in the fundamental QCD vertices; due to thei…
Schwinger-Dyson truncations in the all-soft limit: a case study
A. C. Aguilar, M. N. Ferreira, B. M. Oliveira +1
We study a special Schwinger-Dyson equation in the context of a pure SU(3) Yang-Mills theory, formulated in the background field method. Specifically, we consider the corresponding…
Ghost dynamics in the soft gluon limit
A. C. Aguilar, C. O. Ambrósio, F. De Soto +4
We present a detailed study of the dynamics associated with the ghost sector of quenched QCD in the Landau gauge, where the relevant dynamical equations are supplemented with key i…
