Abstract

We present a measurement of the shape of the boson rapidity distribution for

p \bar{p} \to Z / γ^{*} \to e^{+} e^{-} + X

events at a center-of-mass energy of 1.96 TeV. The measurement is made for events with electron-positron mass

71 < M_{e e} < 111 GeV

and uses

0.4 {fb}^{- 1}

of data collected at the Fermilab Tevatron collider with the D0 detector. This measurement significantly reduces the uncertainties on the rapidity distribution in the forward region compared with previous measurements. Predictions of next-to-next-to-leading order (NNLO) QCD are found to agree well with the data over the full rapidity range.
