Abstract
This talk highlights results selected from the Standard Model research programme of the ATLAS Collaboration at the Large Hadron Collider (LHC). Results using data from pp collisions at $$\sqrt{s}=7,8$$ TeV in LHC Run 1 as well as results using data at centre of mass energy $$\sqrt{s}=13$$ TeV in LHC Run 2 are covered. The status of cross section measurements from soft QCD processes and jet production as well as photon production are presented. The presentation extends to vector boson production with associated jets. Precision measurements of the production of W and Z bosons, including a first measurement of the mass of the W bosons, $$m_W$$ , are discussed. The programme to measure electroweak processes with di-boson and tri-boson final states is outlined. All presented measurements are compatible with Standard Model predictions and allow further constraints.
Highlights
The strong and electroweak sectors are central components of the Standard Model (SM) of particle physics
The high precision and large data statistics available to the ATLAS Collaboration [1] at the LHC [2] allow to further our understanding of these processes from a few charged particles in the non-perturbative to the perturbative regime manifested by high jet multiplicities
The electroweak force is intricately connected to the mechanism of electroweak symmetry-breaking (EWSB)

With excellent progress on the det√ector understanding in recent years, the data from the LHC Run 1 with s = 7, 8 TeV are exploited to their full potential and provide precision measurements of str√ong and electroweak processes at that energy.
