Such long-lived neutral particles occur in many extensions to the Standard Model. The analysis uses either $10.8 ~\\mathrm{fb^{-1}}$ or $33.0 ~\\mathrm{fb^{-1}}$ of data (depending on the trigger) recorded in 2016 at the LHC with the ATLAS detector in proton--proton collisions at a centre-of-mass energy of $13 ~\\mathrm{TeV}$. No significant excess in data is observed, and limits are reported on the production cross section times branching ratio as a function of the proper decay length of the long-lived particles.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.86552.v1/t1","@type":"Dataset","description":"Trigger efficiency of simulated signal events as a function of the LLP $p_T$ for a
