Probing low-x with Drell-Yan events at LHCb

The prospects for reconstructing and selecting $q\bar{q}\rightarrow\gamma^{\star}/Z \rightarrow \mu\mu$ events at LHCb are discussed. Due to the high rapidity coverage and low momentum trigger thresholds of the LHCb detector, these events will probe a unique kinematic region and have the potential to constrain the proton parton distribution functions (PDFs) down to Bjorken-x values of $10^{-6}$.
