Electroweak, QCD and flavour physics studies with ATLAS data from Run 2 of the LHC

Abstract

A summary of precision measurements sensitive to electroweak, QCD and quark-flavoureffects performed by the ATLAS Collaboration at the Large Hadron Collider is reported.The measurements are predominantly performed on proton-proton (pp) collision datarecorded at a centre-of-mass energy of 13 TeV taken from 2015 to 2018, with anintegrated luminosity of up to 140 fb-1, with some results based on pp and Pb+Pbdata recorded at lower nucleon centre-of-mass energies. The results cover a wide rangeof topics, from strong production of particles at low energies and the spectroscopy ofhadrons to perturbative QCD with hadronic jets and electroweak and strong productionof single and multiple vector bosons. They provide precise measurements of fundamentalconstants and stringent tests of the Standard Model with unprecedented precision and inenergy ranges never explored before. They are also used to explore the proton structureand to perform model-independent searches for new physics.
