ATLAS measurements of vector boson production

Vector boson production in pp collisions at 7, 8 and 13 TeV has been extensively studied by ATLAS. Recent results include the precision measurements of the transverse momentum of the Z/gamma* boson production, sensitive to soft resummation effects, hard jet emissions and electroweak corrections.

Sumario:Vector boson production in pp collisions at 7, 8 and 13 TeV has been extensively studied by ATLAS. Recent results include the precision measurements of the transverse momentum of the Z/gamma* boson production, sensitive to soft resummation effects, hard jet emissions and electroweak corrections. A precise measurement of the angular coefficients of the Z­boson production tests the underlying QCD dynamics of the Drell­Yan process. A first measurement of the inclusive W and Z cross section at a cms energy of 13TeV has been derived. The Production of jets in association with a vector boson is an important process to study QCD in a multi­scale environment. Cross sections, differential in several kinematics variables, have been measured with the ATLAS detector and compared to state­of­the­art QCD calculations and Monte Carlo simulations. First measurements of vector boson + jets production have been performed at cms energies of 13TeV. An overview of these results is given.
