  "abstract": "Single inclusive hadron suppression in high-energy heavy-ion collisions provides a sensitive probe of parton energy loss and jet transport coefficient in quark-gluon plasma (QGP). System size dependence of jet quenching can provide further constraints on the dynamics of jet quenching and parton energy loss. Motivated by recent experiments on light-ion collisions at the Large Hadron Collider (LHC), we perform a systematic study of single-inclusive hadron suppression in O+O, Ne+Ne, Xe+Xe and Pb+Pb collisions at the LHC energies. The calculations are carried out within the next-to-leading-order perturbative QCD model, incorporating the nuclear modified initial-state parton distributions, final-state parton energy loss in the higher-twist approach and the temperature dependence of the jet transport coefficient $\\hat q/T^3$ from the Bayesian analyses of previous experimental data at the Relativistic Heavy-ion Collider (RHIC) and LHC. Our model calculations can simultaneously describe the measured single-inclusive charged hadron $R_{AA}$ in O+O, Ne+Ne, Xe+Xe and Pb+Pb collisions over a broad range of event centralities and in the minimum-bias events. We further illustrate the system size dependence of jet quenching through the ratio $R_{\\mathrm{NeNe}}/R_{\\mathrm{OO}}$ and the modification factors $R_{AA}$ as a function of $\\langle N_{\\mathrm{coll}} \\rangle$ which follow a common behavior at fixed $p_{\\rm T}$, indicating the formation of QGP even in the smallest collision systems.",
