| \footnotesize Light-particle multiplicity distributions (left) and elliptic flow $v_{2}$ (right) as a function of $\eta_{\rm lab}$ for fixed-target Pb-Pb collisions, in the centrality range 20-30\%. Pions (kaons, protons and antiprotons) are represented as black (red, blue, pink) dots, respectively. In the right panel, the statistical uncertainties on the $v_{2}$ coefficients (vertical uncertainty bars) have been computed in the ALICE central-barrel and LHCb detector acceptances, assuming the collection of 10$^{8}$ minimum bias events. |
| \footnotesize Left panel: Dimuon invariant-mass distribution in the $\Upsilon(nS)$ region after combinatorial background subtraction, in Pb-Xe collisions at $\sqrt{s_{NN}}$ = 72 GeV ($\cal{L}_{\rm int}$~=~30 nb$^{-1}$). Single muons are required to have $p_{T} >$~0.7~GeV/c and dimuons to be within 3 $< y_{\rm lab} <$ 5. Right panel: Projection of the statistical uncertainties (vertical bars) on the nuclear modification factor in pXe collisions (black square), Pb-Xe collisions (blue dot) for $\Upsilon(1S)$, $\Upsilon(2S)$ and $\Upsilon(3S)$, in the rapidity range 3 $< y_{\rm lab} <$ 5. |
| \footnotesize Left panel: D$^{0}$ meson yield per year as a function of $p_{\rm T}$ in fixed-target pp collisions at $\sqrt{s}$~=~115~GeV, for three D$^{0}$ rapidity ranges: 2 $< y_{lab} <$ 3 (red line), 3 $< y_{lab} <$ 4 (green dashed line), 4 $< y_{lab} <$ 5 (blue dotted line). Right panel: Relative uncertainty on the D$^{0}$ meson yield due to the IC content of the proton as a function of $p_{\rm T}$. The vertical black lines correspond to the statistical projections of the AFTER@LHC yearly D$^{0}$ meson yield in pp collisions at $\sqrt{s}$~=~115 GeV, in 2 $< y_{lab} <$ 3. |
