 SEARCHES FOR DARK MATTER AT THE LHC / Tapper, Alexander (Imperial Coll., London) /ATLAS and CMS Collaborations Astrophysical measurements show that around 85\% of the universe consists of dark matter, the origin of which is unknown. Dedicated experiments search for dark matter in the cosmos interacting directly and through annihilation [...] CMS-CR-2019-210.- Geneva : CERN, 2019 - 9 p.

 Status of searches in the long-lived particle and dark sectors, including full run-2 and HL-LHC prospects / Alimena, Juliette (Ohio State U.) /ATLAS, CMS and LHCB Collaborations Particles beyond the standard model can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at the LHC at CERN, these long-lived particles (LLPs) can decay far from the primary proton-proton interaction, or even completely pass through the detector before decaying.
