Abstract
These proceedings summarise ATLAS measurements of properties of the strong and electroweak forces in proton-proton collisions at 7 and 8 TeV during Run-1 at the LHC. The specific measurements presented here are concerned with the gauge symmetries in the Standard Model and related parameters, starting with the production cross section of a W boson in association with jets, the forward-backward asymmetry in the production of Z/γ∗ decaying to electrons or muons and extraction of the effective weak mixing angle. Then a number of measurements specifically probing electroweak processes at very high energies are presented, including the first measurement of triple gauge boson production pprightarrow W(lnu )gamma gamma , the production of a leptonically decaying W boson in association with W or Z boson decaying to jets, electroweak production of two jets in association with a Z boson, and same-electric-charge diboson production in association with two jets providing the first evidence of electroweak vector boson scattering.
