Heavy-ion physics and strong interactions at LHCb

The LHCb experiment is a single-arm spectrometer designed for the study of heavy flavour physics at the LHC, but also an excellent general purpose experiment for the study of quantum chromodynamics in the forward region. The forward acceptance make the LHCb data particular interesting for many applications in astroparticle physics, which are dominated by forward hadron production. We present four analyses that investigate aspects of strong interactions in pp, pPb, and PbPb collisions from 5.02 TeV to 13 TeV.
