Secondary cascades in the TAXN absorber produce a substantial millicharged particle flux that complements primary production and boosts FORMOSA signals by ~50% for m_χ below 0.1 GeV.
Dark pions stabilized by U(1) flavor symmetry in an SU(3)/SO(3) dark sector obtain the correct thermal relic density through up-scatterings to heavier mesons and dark eta decays, producing LHC signals from long-lived particle showers.
DELIGHT-SHIELD uses a dedicated shield followed by tracking to suppress hadronic and electromagnetic backgrounds by up to seven orders of magnitude, reaching branching ratio sensitivity of O(10^{-9}) for h to phi phi in a dark scalar model.
ANUBIS offers the highest projected sensitivity for detecting single-photon signatures from long-lived neutralinos at the LHC among several remote detector proposals, based on six benchmark scenarios.
In a vector dark matter extension of the Higgs portal, far detectors at colliders can probe otherwise inaccessible parameter space and set novel bounds on the reheating temperature.
Tera-Z factories can produce millions of heavy neutral leptons and billions of axion-like particles under optimistic assumptions, turning them into exotics factories for discovery and detailed study.
STCF can reach |V_eN|^2 values one to two orders of magnitude below current bounds for heavy neutral leptons via displaced-vertex searches from ALP decays in D-meson production.
Thermal corrections to reheating and freeze-in DM production rates are generally small in the computable regime but can be large in constructed counter-examples.
Natural SUSY with axino LSP allows viable mixed axion-axino dark matter matching the observed abundance for axino masses near 100 keV and PQ scales of 10^11 to 3x10^12 GeV in DFSZ and KSVZ models.
Mixing angle between toponium and elementary field Ψ is constrained to |θ| ≤ 13° (minimal model) or |θ| ≤ 1° (2HDM Type II/Y) to fit CMS ttbar excess under MPP.
Magnetic monopoles are theoretically well-motivated but remain unobserved after extensive searches in cosmic rays and at particle colliders such as the LHC.
