Long-lived particles can manifest themselves at the LHC via "displaced vertices" - several charged tracks originating from a position separated from the proton interaction point by a macroscopic distance. Here we demonstrate a potential of the muon trackers at the CMS experiment for displaced vertex searches. We use heavy neutral leptons and Chern-Simons portal as two examples of long-lived particles for which the CMS muon tracker can provide essential information about their properties.

  1. Constraining Heavy Neutral Leptons Coupled to the Tau-Neutrino Flavor at the Large Hadron Collider

    hep-ph 2025-10 conditional novelty 6.0 of 10

    DV searches with no prompt-lepton tag can probe HNLs with dominant tau-neutrino mixing at the LHC, improving existing bounds by more than an order of magnitude at Run 2 luminosity.

  2. Searches for heavy neutral lepton decays at spallation neutron sources

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Current and future COHERENT detectors at the SNS can set competitive limits on HNL–neutrino mixings through pion/muon DAR production and in-detector e+e− decays, with muon mixing offering the strongest near-term reach.
