Strangeness Enhancement in Fixed-Target Pb-Ne Collisions with LHCb SMOG Experiment

At sufficiently high temperature and energy density, nuclear matter converts to a phase where quarks and gluons are not confined: the Quark-Gluon Plasma (QGP). Such a state is produced in the laboratory with ultra-relativistic collisions of heavy nuclei, resulting in an enhanced strange hadrons' production. Strangeness enhancement has been proposed as a test of the Quark-Gluon Plasma formation due to: (i) the dominance of the $gg \rightarrow s\bar{s}$ channel and (ii) the high gluon and high strange quark densities in QGP. Here I report on the analysis of the samples related to fixed-target Pb-Ne and p-Ne collisions at $\sqrt{s_{NN}} = 68.6$ GeV collected with SMOG at LHCb.
