Heavy-Ion and Fixed-Target Physics in LHCb

Selected results of the LHCb experiment on heavy ion collisions studied in the collider and fixed-target modes are presented. The clear evidence of the impact of the production mechanism (prompt/delayed, p-p or p-Pb systems) on the $_{pT}$ and rapidity distributions for $_{J/ф, D}$$^{0}$ and ϒ(ns) species is demonstrated. The interpretation of the observations in frames of theoretical models is briefly discussed. Some original results, as well as prospects of fixed-target mode studies, are presented.
