Abstract
Particles beyond the Standard Model (SM) can have generically longer lifetimes than SM particles at the weak scale. These long-lived particles (LLPs) can decay far from the interaction vertex of the primary proton-proton collision when produced at experiments such as CERN's Large Hadron Collider (LHC). Here we report on searches for LLPs that are assumed to decay to a pair of standard model quarks that are identified as displaced jets with the ATLAS, CMS, and LHCb experiments. No significant discrepancies with respect to the Standard Model predictions have been found in data, so that limits for several benchmark signals have been set. In particular, the results are interpreted in the context of exotic decays of the Higgs boson to a pair of scalar LLPs (H $\rightarrow$ SS) with a mass of 125 GeV and for masses between 200 GeV and 1 TeV.
