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 at reduced system size. In this work, we study hadron and jet suppression in O+O collisions at RHIC energy $\sqrt{s}$ = 200 GeV to systematically quantify jet energy loss and jet anisotropic flow within the Linear Boltzmann Transport (LBT) model, coupled to an event-by-event (3+1)D hydrodynamic background. We further present predictions for jet energy loss in O+O collisions at the LHC energy $\sqrt{s}$ =5.36 TeV, enabling a unified comparison of jet suppression and jet $v_n$ across disparate energy scales. Finally, by combining the O+O results with corresponding Pb+Pb calculations, we examine the path-length dependence of jet quenching and assess how medium size and geometry control the observed suppression and anisotropy.
