  The multiplicity percentile dependence of cumulants, of net-proton number
distributions in Au$-$Au collisions at $\sqrt{s_{NN}} = $ 200 GeV and Pb$-$Pb
collisions at $\sqrt{s_{NN}} = $ 2.76 TeV has been investigated using the
Angantyr model (the heavy-ion extension of the \textsc{Pythia 8} model). The
effects of finite transverse momentum ($p_{\mathrm T}$) and pseudorapidity
($\eta$) acceptance on the net-proton cumulants have also been studied.
Furthermore, the effects of the hydrodynamic expansion and feed down from weak
decays were explored. It was found that radial flow has substantial impact on
the cumulants and their ratios, while weak decays have a finite but relatively
smaller effect. The obtained values of cumulants and their ratios with the
Angantyr model, where the formation of thermalized medium is not assumed can
serve as a baseline for future measurements.
