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…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
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…
