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…

Feebly Interacting Particles: FIPs at LHCb

J. Alimena, J. Boyd, G. Cacciapaglia +36

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader part…

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…

Invariant relativistic kinematics: Phase space triangulation

Jan Hajer

The calculation of particle decay widths and scattering cross sections naturally decomposes into a quantum mechanical amplitude and a relativistic phase space (PS). This PS can be…

New Physics Search at the CEPC: a General Perspective

Xiaocong Ai, Stefan Antusch, Peter Athron +211

The Circular Electron-Positron Collider (CEPC), a proposed next-generation Higgs factory, provides new opportunities to explore physics beyond the Standard Model (SM). With its cle…

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…

Feebly Interacting Particles: FIPs 2022 workshop report

C. Antel, M. Battaglieri, J. Beacham +75

Particle physics today faces the challenge of explaining the mystery of dark matter, the origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the a…
