  Measurements of the normalized rapidity (y) and transverse momentum (qT)
distributions of Drell-Yan muon and electron pairs in the Z-boson mass region
(60<M(ll)<120 GeV) are reported. The results are obtained using a data sample
of proton-proton collisions at a center-of-mass energy of 7 TeV, collected by
the CMS experiment at the LHC, corresponding to an integrated luminosity of 36
inverse picobarns. The distributions are measured over the ranges |y|<3.5 and
qT<600 GeV and compared with QCD calculations using recent parton distribution
functions. Overall agreement is observed between the models and data for the
rapidity distribution, while no single model describes the Z
transverse-momentum distribution over the full range.
