Description
The production of the W and Z bosons is the standard candle process at the LHC.
The differential Z/gamma∗ and the charge dependent W+ and W- cross sections
are provided in bins of boson rapidity and lepton pseudorapidity.
A measurement of angular correlations in Drell–Yan lepton pairs for neutral current process via the
phi* observable is also presented. This variable probes the same physics as the Z/gamma* boson
transverse momentum (pT) with a better experimental resolution, especially for low transverse momenta.
Neutral current Drell Yan off-Z resonance peak cross section is sensitive to the proton parton distribution
functions, in particular to u-bar quark density. An overview of these results is given.
