The inclusive top quark pair (tt¯) production cross-section σtt¯ has been measured in proton–proton collisions at s√=13TeV, using 36.1 fb−1 of data collected in 2015–2016 by the ATLAS experiment at the LHC. Using events ...

A measurement of observables sensitive to spin correlations in tt¯ production is presented, using 36.1 fb−1 of pp collision data at s√=13 TeV recorded with the ATLAS detector at the Large Hadron Collider. Differential ...

The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many ...

A search for flavour-changing neutral current (FCNC) events via the coupling of a top quark, a photon, and an up or charm quark is presented using 81fb−1of proton–proton collision data taken at a centre-of-mass energy of ...

A search for new resonances decaying into a pair of jets is reported using the dataset of proton-proton collisions recorded at s√ = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, ...

A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139  fb−1 of proton-proton collisions at √s=13  TeV recorded with the ATLAS detector. The search ...

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 ...

A search for supersymmetric partners of gluons and quarks is presented, involving signatures with jets and either two isolated leptons (electrons or muons) with the same electric charge, or at least three isolated leptons. ...

A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in proton−proton collisions at the Large Hadron Collider at √s=13  TeV is presented. The analysis utilizes the dominant W→q¯q′ or Z→q¯q ...
