| This dissertation describes a measurement of the shape of the boson transverse momentum distribution in pp¯ → Z/gamma* → e+e- + X events at a center-of-mass energy of 1.96 TeV. The measurement is made for events with electron-positron mass between 70 < M ee < 110 GeV/c2 and uses 976 pb-1 of data collected at the Fermilab Tevatron collider with the DO detector. The shape is measured both for the inclusive sample and for the subset of events containing a boson with large rapidity. The large-rapidity distribution shows better agreement with theory when the calculation is done using traditional Collins-Soper-Sterman resummation than when using a recent resummed form factor with modifications in the small-x region. |
