Query: Forward physics with the LHCb experiment   Due to its unique pseudorapidity coverage and the ability to perform
measurements at low transverse momenta, the LHCb detector allows a unique
insight into particle production in the forward region at the LHC. Using large
samples of proton-proton collision data accumulated at sqrt(s)=7 TeV, the LHCb
collaboration has performed a series of dedicated analyses providing important
input to the knowledge of the parton density functions, underlying event
activity, low Bjorken-x QCD dynamics and exclusive processes. Some of these are
briefly summarised here.
