Resumen:
A measurement of the Z/gamma* transverse momentum (p_T^Z)) distribution
in proton-proton collisions at sqrt(s)=7 TeV is presented using
Z/gamma*->e+e- and Z/gamma*->mu+mu- decays collected with the
ATLAS detector in data sets with integrated luminosities of 35 pb^-1 and
40 pb^-1, respectively. The normalized differential cross sections are
measured separately for electron and muon decay channels as well as for
their combination up to p_T^Z of 350 GeV for invariant dilepton masses
66 GeV<m_ll<116 GeV. The measurement is compared to predictions of
perturbative QCD and various event generators. The prediction of
resummed QCD combined with fixed order perturbative QCD is found to be
in good agreement with the data.
