Název v původním jazyce

Search for a resonance decaying into a scalar particle and a Higgs boson in final states with leptons and two photons in proton-proton collisions at s = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for a hypothetical heavy scalar particle, X, decaying into a singlet scalar particle, S, and a Standard Model Higgs boson, H, using 140 fb-1 of proton-proton collision data at the centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the LHC is 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 bosons originating from the S particle, S -> W±W-/+/ZZ, and two photons from the Higgs boson decay, H -> γγ. No signifcant excess is observed above the expected Standard Model background. The observed (expected) upper limits at the 95% confdence level on the crosssection for gg -> X -> SH, assuming the same S -> WW/ZZ branching ratios as for a SM-like heavy Higgs boson, are between 530 (800) fb and 120 (170) fb.
