Electron and photon triggers covering transverse energies from 5 GeV to several TeV are essential for the ATLAS experiment to record signals for a wide variety of physics: from Standard Model processes to searches for ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
Azimuthal anisotropies of muons from charm and bottom hadron decays are measured in Pb+Pb collisions at √sNN=5.02TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2018 with ...

This paper presents results of searches for the electroweak production of supersymmetric particles in models with compressed mass spectra. The searches use 139 fb−1 of √s=13 TeV proton-proton collision data collected by ...

The production of a prompt photon in association with a Z boson is studied in proton-proton collisions at a centre-of-mass energy s√ = 13 TeV. The analysis uses a data sample with an integrated luminosity of 139 fb−1 ...

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 dijet resonances in events with at least one isolated charged lepon is performed using 139 fb−1 of s√ = 13 TeV proton-proton collision data recorded by the ATLAS detector at the LHC. The dijet invariant-mass ...
