Measurement of the Drell-Yan differential cross section and forward-backward asymmetry in proton antiproton decays to electron positron events using the DZero detector.

摘要

We present measurements of the inclusive Drell-Yan e+e- differential cross section (dsigma/dMe+e -) and forward-backward asymmetry (AFB ) as a function of the dielectron invariant mass over the range 70--400 GeV/c2. The data sample consists of 177.3 pb-1 of pp¯ collisions at s = 1.96 TeV collected by the DO detector. The results are consistent with the predictions of the standard model.
