    <description descriptionType="Abstract">&lt;p&gt;This paper describes a search for pairs of neutral, long-lived particles decaying in the ATLAS calorimeter. Long-lived particles occur in many extensions to the Standard Model and may elude searches for new promptly decaying particles. The analysis considers neutral, long-lived scalars with masses between 5 and 400 GeV, produced from decays of heavy bosons with masses between   $125$  and   $1000$  GeV, where the long-lived scalars decay into Standard Model fermions. The analysis uses either   $10.8\phantom{\rule{3.33333pt}{0ex}}{\text{fb}}^{-1}$  or   $33.0\phantom{\rule{3.33333pt}{0ex}}{\text{fb}}^{-1}$  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 TeV. No significant excess 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.&lt;/p&gt;</description>
