Heavy-ion and fixed-target physics at LHCb

The LHCb collaboration pursues a full physics program studying dense QCD with both beam-beam and fixed-target collisions. The forward design of the LHCb spectrometer allows probing the low-x region of the nucleus, while high vertexing precision and full particle ID guarantee the reconstruction of a wide range of hadrons down to very low transverse momentum. In this contribution we present the recent LHCb results including open charm and charmonia production in fixed target collisions and Bose-Einstein correlation effects in proton-lead collisions.
