SMOG at LHCb: experimental results

We report the latest results obtained by the LHCb experiment in its fixed-target configuration using the System for Measuring Overlap with Gas (SMOG).These results use the $p\text{He}$(2016), $p\text{Ne}$(2017) and $\text{PbNe}$ (2018) samples collected at a center of mass energy of $\sqrt{s_\text{NN}}= 110$ GeV and $\sqrt{s_\text{NN}}= 68.5$ GeV (for $p\text{Ne}$ and $\text{PbNe}$) respectively. The implications of these experimental results on theory are discussed, with a focus on the impact on quantum chromodynamics (QCD) and on theoretical predictions on the antiprotons flux originating from cosmic rays spallation on the interstellar medium
