Study of the normalized transverse momentum distribution of W bosons produced in pp collisions at √s=1.96 TeV
We present a study of the normalized transverse momentum distribution of W bosons produced in pp collisions, using data corresponding to an integrated luminosity of 4.35 fb−1 collected with the D0 detector at the Fermilab Tevatron collider at √s=1.96 TeV. The measurement focuses on the transverse momentum region below 15 GeV, which is of special interest for electroweak precision measurements; it relies on the same detector calibration methods which were used for the precision measurement of the W boson mass. The measured distribution is compared to different QCD predictions and a procedure is given to allow the comparison of any further theoretical models to the D0 data.
