ATLAS Drell-Yan measurements

Differential neutral current Drell-Yan cross sections are sensitive to the parton distribution functions of the proton as well as QCD and electroweak corrections. Measurements by ATLAS cover the three distinct kinematic regions at the $Z$ resonance peak, below and above. The results are compared to state-of-the-art calculations. Precise measurements of the transverse momentum of $Z/\gamma^\star$ bosons and the complementary $\phi^\star$ observable are sensitive to soft resummation effects for small momentum transfers and to multiple hard jet emissions for large momentum transfers, probing QCD in a unique way. The results of the measurements are used to constrain non-perturbative modelling of the low $p_T$ region in MC generators.
