The STAR experiment at the Relativistic Heavy Ion Collider presents measurements of correlations between charged hadron triggers of high transverse momenta (7<𝑝&sub(T)<30  GeV/𝑐) with recoiling charged hadrons (3<𝑝&sub(T)<7  GeV/𝑐) or charged-particle jets (𝑝&sub(T,jet)>8  GeV/𝑐) in event-activity selected O+O collisions at √𝑠NN =200  GeV. Yields of associated hadrons and jets, normalized by the number of trigger hadrons, are suppressed by approximately 20% in high event activity relative to low event activity collisions, with an absence of suppression excluded with high significance. This suppression corresponds to a shift in 𝑝&sub(T) of 0.70±0.15⁢(stat.)±0.10⁢(syst.)  GeV/𝑐 for large-radius charged-particle jets (𝑅 =0.5), quantifying their energy redistribution due to final-state interactions. These measurements provide strong evidence for jet quenching in O+O collisions at √𝑠&sub(NN) =200  GeV, offering new insight into quark-gluon plasma formation in small collision systems.
