Standard Model highlights at ATLAS / Kivernyk, Oleh (University of Bonn (DE))
This contribution reviews the latest high-precision measurements from ATLAS, which include an improved measurement of the W-boson mass, a new method for measuring double-differential $p_T$ and rapidity cross sections of the Z boson and determining the strong coupling constant, and measurements of fiducial and differential $W^+W^-$ cross sections..
