Measurement of 1/sigma dsigma/dy for Z boson/gamma* to positron-electron and X meson at center of mass energy = 1.96 TeV.

摘要

Author presents the measurement of pp¯ → Z/gamma* → e+ e- + X inclusive differential cross section as a function of boson rapidity. The data, which correspond to an integrated luminosity of 0.4 fb-1, were collected with DO detector at Tevatron pp¯ collider. At the Run II energy of s = 1.96 TeV, Z bosons are produced with rapidity out to +/- 3. The cross section is measured in a mass range between 71 to 111 GeV for the allowed kinematic range.
