Key Details

Heavy neutral leptons could explain dark matter or other phenomena

Long-lived particles would produce unique displaced signatures

Vector-like quarks could stabilize Higgs boson mass

No signals seen yet, but limits further constrain models

Searches for exotic particles at CERN

This paper summarizes searches by the ATLAS and CMS experiments at CERN's Large Hadron Collider for three types of hypothetical exotic particles that go beyond the Standard Model of particle physics: heavy neutral leptons, long-lived particles, and vector-like quarks. No signals have been observed yet, but improved limits have been set, constraining some theoretical models and mass/lifetime ranges.
