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.}, keywords = {p p: colliding beams (INSPIRE) / neutral particle: long-lived (INSPIRE) / Z0: associated production (INSPIRE) / Z0: leptonic decay (INSPIRE) / electron: pair production (INSPIRE) / muon: pair production (INSPIRE) / boson: scalar (INSPIRE) / calorimeter: hadronic (INSPIRE) / p p: scattering (INSPIRE) / cross section: scalar (INSPIRE) / ATLAS (INSPIRE) / channel cross section: branching ratio: upper limit (INSPIRE) / mass dependence (INSPIRE) / Higgs particle: branching ratio: upper limit (INSPIRE) / CERN LHC Coll (INSPIRE) / background (INSPIRE) / experimental results (INSPIRE) / 13000 GeV-cms (INSPIRE)}, cin = {ATLAS}, ddc = {530}, cid = {I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611)}, pid = {G:(DE-HGF)POF3-611}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101}, typ = {PUB:(DE-HGF)29 / PUB:(DE-HGF)16}, eprint = {1811.02542}, howpublished = {arXiv:1811.02542}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1811.02542;\%\%$}, pubmed = {pmid:31050493}, UT = {WOS:000464756200003}, doi = {10.1103/PhysRevLett.122.151801}, url = {https://bib-pubdb1.desy.de/record/424937}, }
