Provides constraints on parton distribution functions at low x

Enhances understanding of forward region physics

Abstract

Results for $W$ and $Z$ boson production from $pp$ collisions at $\sqrt{s} = 7$ TeV in the LHCb experiment are presented. Due to LHCb's unique forward acceptance in pseudorapidity of $2.0 \leq \eta \leq 4.5$ these results are a test of the Standard Model in the forward region, and can be used to better constrain parton density functions in the low $x$ kinematic regime.
