Measurement of the Shape of the Boson-Transverse Momentum Distribution in pp{yields}Z/{gamma}*{yields}e{sup +}e{sup -}+X Events Produced at {radical}(s)=1.96 TeV

We present a measurement of the shape of the Z/{gamma}* boson transverse momentum (q{sub T}) distribution in pp{yields}Z/{gamma}*{yields}e{sup +}e{sup -}+X events at a center-of-mass energy of 1.96 TeV using 0.98 fb{sup -1} of data collected with the D0 detector at the Fermilab Tevatron collider. The data are found to be consistent with the resummation prediction at low q{sub T}, but above the perturbative QCD calculation in the region of q{sub T}>30 GeV/c. Using events with q{sub T}<30 GeV/c, we extract the value of g{sub 2}, one of the nonperturbative parameters for the resummation calculation. Data at large boson rapidity y are compared with the prediction of resummation and with alternative models that employ a resummed form factor with modifications in the small Bjorken x region of the proton wave function.
