(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for Higgs boson decays into a Z boson and a light resonance in two-lepton plus jet events is performed, using a pp collision dataset with an integrated luminosity of 139 fb−1 collected at √s=13 TeV by the ATLAS ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A study of the charge conjugation and parity (CP) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel (H→γγ), and their production ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for heavy neutral Higgs bosons produced in association with one or two b-quarks and decaying to b-quark pairs is presented using 27.8 fb−1 of √s=13 TeV proton-proton collision data recorded by the ATLAS detector ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for long-lived particles decaying into hadrons and at least one muon is presented. The analysis selects events that pass a muon or missing-transverse-momentum trigger and contain a displaced muon track and a ...

A search for a chargino-neutralino pair decaying via the 125 GeV Higgs boson into photons is presented. The study is based on the data collected between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
Inclusive and differential fiducial cross sections of the Higgs boson are measured in the H→ZZ∗→4ℓ (ℓ=e,μ) decay channel. The results are based on proton-proton collision data produced at the Large Hadron Collider at a ...

The observation of forward proton scattering in association with lepton pairs (e+e−+p or μ+μ−+p) produced via photon fusion is presented. The scattered proton is detected by the ATLAS Forward Proton spectrometer, while the ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
Higgs boson properties are studied in the four-lepton decay channel (where lepton = e, μ) using 139 fb−1 of proton–proton collision data recorded at s√=13 TeV by the ATLAS experiment at the Large Hadron Collider. The ...

This Letter describes a search for narrowly resonant new physics using a machine-learning anomaly detection procedure that does not rely on signal simulations for developing the analysis selection. Weakly supervised learning ...
