Long-lived light particles (LLLPs) appear in many extensions of the standard model. LLLPs are usually motivated by the observed small neutrino masses, by dark matter or both. Typical examples for fermionic LLLPs (a.k.a. heavy neutral fermions, HNFs) are sterile neutrinos or the lightest neutralino in R-parity violating supersymmetry. The high luminosity LHC is expected to deliver up to 3/ab of data. Searches for LLLPs in dedicated experiments at the LHC could then probe the parameter space of LLLP models with unprecedented sensitivity. Here, we compare the prospects of several recent experimental proposals, FASER, CODEX-b and MATHUSLA, to search for HNFs and discuss their relative merits.

  1. Detecting and Studying High-Energy Collider Neutrinos with FASER at the LHC

    hep-ex 2019-08 accept novelty 7.0 of 10

    FASERν is predicted to detect thousands of collider neutrinos at the LHC and measure their cross sections at TeV energies, closing a gap in neutrino measurements.

  2. A frequentist analysis of three right-handed neutrinos with GAMBIT

    hep-ph 2019-08 conditional novelty 7.0 of 10

    A comprehensive frequentist global fit maps the currently allowed mass and mixing space for three right-handed neutrinos between 60 MeV and 500 GeV and finds no significant new physics.

  3. Probing light neutralinos from pair-produced sleptons with displaced vertices at the high-luminosity LHC

    hep-ph 2025-05 conditional novelty 6.0 of 10

    A displaced-vertex search for slepton pair production at the HL-LHC can probe RPV coupling lambda-prime-111 down to about 1e-7 and neutralino masses up to roughly 1 TeV, far beyond single-slepton production.

  4. Searching for a Sterile Neutrino in Tau Decays at B-factories

    hep-ph 2019-08 conditional novelty 6.0 of 10

    A displaced-vertex search in tau decays at BaBar, Belle, and Belle II could set limits on tau-mixing sterile neutrinos below the current DELPHI bound.

  5. Heavy Neutral Leptons without Prejudice

    hep-ph 2024-12 conditional novelty 5.0 of 10

    HL-LHC and FCC-ee can probe HNL Yukawa couplings down to y^2 near 10^-4 to 10^-6 depending on mass; at zero mixing, Higgs width precision is the strongest constraint and the two colliders have comparable reach.

  6. Displaced heavy neutrinos from $Z'$ decays at the LHC

    hep-ph 2019-08 conditional novelty 5.0 of 10

    Displaced vertex searches at the HL-LHC could probe heavy neutrino mixings down to |V_lN|^2 ~ 10^-17 for Z'-produced neutrinos in U(1)_X and U(1)_{B-L} models.

  7. CODEX-b: Opening New Windows to the Long-Lived Particle Frontier at the LHC

    hep-ex 2025-05 conditional novelty 3.0 of 10

    CODEX-b is a proposed 10-meter cube near LHCb for catching long-lived new particles, and this ESPP paper presents optimized cheaper designs, cost and timeline estimates, and the CODEX-β demonstrator already installed ...
