\begin{document}$ \pi^0 $\end{document}, η, and ϕ in the most central (0%–5%) Xe+Xe collisions at \begin{document}$\sqrt{s_{NN}}$\end{document} = 5.44 TeV is investigated in the framework of the perturbative QCD (pQCD) improved parton model at an accuracy of next-to-leading order (NLO). The jet quenching effect is effectively incorporated by medium-modified fragmentation functions via the higher-twist approach. Predictions of the nuclear modification factors of \begin{document}$ \pi^0 $\end{document}, η, and ϕ as functions of the transverse momentum \begin{document}$ p_{\rm{T}} $\end{document} are made with the jet transport parameter \begin{document}$ \hat{q}_0 $\end{document}, which is extracted from the available experimental data of charged hadrons provided by ALICE and CMS. The particle ratios \begin{document}$ \eta/\pi^0,\ \phi/\pi^0 $\end{document} as functions of \begin{document}$ p_{\rm{T}} $\end{document} in Xe+Xe collisions at \begin{document}$\sqrt{s_{NN}}$\end{document} = 5.44 TeV as well as in 0%–5% Pb + Pb collisions at \begin{document}$\sqrt{s_{NN}}$\end{document} = 5.02 TeV are also presented. The numerical simulations of the scaled ratios of charged hadron production in the Xe+Xe 5.44 TeV system over those in the Pb+Pb 5.02 TeV system give a good description of the CMS data, and the scaled ratios of \begin{document}$ \pi^0 $\end{document}, η, and ϕ production coincide with the curve of charged hadron production."> Particle production at large <i>p</i><i><sub>T</sub></i> in Xe+Xe collisions with jet quenching using the higher twist approach -
