Search for neutral long-lived particles that decay into displaced jets in the ATLAS calorimeter in association with leptons or jets using pp collisions at √s = 13 TeV
Original language description
A search for a hypothetical heavy scalar particle, X, decaying into a singlet scalarparticle, S, and a Standard Model Higgs boson, H, using 140 fb-1 of proton-proton collisiondata at the centre-of-mass energy of 13TeV recorded with the ATLAS detector at the LHCis presented. The explored mass range is 300 <= mX <= 1000 GeV and 170 <= mS <= 500 GeV.The signature of this search is one or two leptons (e or μ) from the decay of vector bosonsoriginating from the S particle, S RIGHTWARDS ARROW W+-WMINUS-OR-PLUS SIGN/ZZ, and two photons from the Higgs bosondecay, H RIGHTWARDS ARROW γγ. No significant excess is observed above the expected Standard Modelbackground. The observed (expected) upper limits at the 95% confidence level on the crosssectionfor gg RIGHTWARDS ARROW X RIGHTWARDS ARROW SH, assuming the same S RIGHTWARDS ARROW WW/ZZ branching ratios as for aSM-like heavy Higgs boson, are between 530 (800) fb and 120 (170) fb.
