Description
The search for quark–gluon plasma (QGP)-like collectivity in small collision systems remains a central goal of high-energy nuclear physics. Recent results from O$+$O collisions suggest that strongly coupled, near-perfect-fluid behavior may emerge even in such small systems, motivating a detailed investigation of jet quenching in systems of reduced size. In this work, we study hadron and jet suppression in O$+$O collisions at the LHC energy $\sqrt{s}=5.36$ TeV to systematically quantify jet energy loss within the Linear Boltzmann Transport (LBT) model, coupled to CCNU-LBNL viscous (CLVisc) (3+1)D hydrodynamic background. We further investigate jet energy loss in O$+$O collisions at RHIC energy $\sqrt{s} = 200$ GeV, enabling a unified comparison of jet suppression across different energy scales. Finally, by comparing the O$+$O results with corresponding Pb$+$Pb calculations, we examine the path-length dependence of jet quenching and assess how medium size governs the observed suppression.
