abstract
We investigate the reach at the LHC to probe light sterile neutrinos with displaced vertices. We focus on sterile neutrinos $N$ with masses $m_{N} \sim $ (5-30) GeV, that are produced in rare decays of the Standard Model gauge bosons and decay inside the inner trackers of the LHC detectors. With a strategy that triggers on the prompt lepton accompanying the $N$ displaced vertex and considers charged tracks associated to it, we show that the 13 TeV LHC with $3000$/fb is able to probe active-sterile neutrino mixings down to $|V_{lN}|^2\approx 10^{-9}$, with $l=e,\mu$, which is an improvement of up to four orders of magnitude when comparing with current experimental limits from trileptons and proposed lepton-jets searches. In the case when $\tau$ mixing is present, mixing angles as low as $|V_{\tau N}|^2 \approx 10^{-8}$ can be accessed.

Dominant Thermal Resonant Mechanism for Low-Scale Leptogenesis
Thermal Resonant Leptogenesis produces the observed baryon asymmetry via a dominant thermal channel from Higgs decays and lepton-doublet coherences, without requiring quasi-degenerate sterile neutrinos.

Probing lepton number violation at FCC-ee
Proposes e+e- to N N-bar to ell+ ell+ 4j signatures at FCC-ee in minimal linear seesaw yielding O(10^3) events with negligible SM background to probe LNV and neutrino mass ordering.

Heavy neutral leptons and top quarks in effective field theory
Long-lived heavy neutral leptons produced via top-quark effective operators could be probed at the HL-LHC up to new-physics scales around 12 TeV at ATLAS and 4.5 TeV at MATHUSLA or ANUBIS.

Simulations of the Sterile Neutrino Oscillations with a Crossing-Width Term
A two-step diagonalization plus a dummy-particle trick lets standard event generators simulate GeV-scale sterile neutrino oscillations with crossing-width terms, and a QFT derivation gives displaced-vertex distances.

Searches for heavy neutral lepton decays at spallation neutron sources
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.

Probing electroweak pair production of heavy neutral leptons with displaced vertices at the LHC
LHC displaced-vertex data can exclude sterile neutrinos with masses 20-230 GeV and mixings down to 4e-14 when they are produced in pairs from higgsino decays.

Heavy Neutral Leptons without Prejudice
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.
