      abstract     = {This Letter presents a search for the production of a
                      long-lived neutral particle (Zd) decaying within the ATLAS
                      hadronic calorimeter, in association with a standard model
                      (SM) Z boson produced via an intermediate scalar boson,
                      where Z→ℓ+ℓ- (ℓ=e, μ). The data used were collected
                      by the ATLAS detector during 2015 and 2016 pp collisions
                      with a center-of-mass energy of s=13  TeV at the Large
                      Hadron Collider and correspond to an integrated luminosity
                      of 36.1±0.8  fb-1. No significant excess of events is
                      observed above the expected background. Limits on the
                      production cross section of the scalar boson times its decay
                      branching fraction into the long-lived neutral particle are
                      derived as a function of the mass of the intermediate scalar
                      boson, the mass of the long-lived neutral particle, and its
                      cτ from a few centimeters to one hundred meters. In the
                      case that the intermediate scalar boson is the SM Higgs
                      boson, its decay branching fraction to a long-lived neutral
                      particle with a cτ approximately between 0.1 and 7 m is
                      excluded with a $95\% confidence$ level up to $10\%$ for
                      mZd between 5 and 15 GeV.},
