Abstract
Charged hadrons in $0.15<{p}_{\ensuremath{\perp}}<4\text{ }\text{ }\mathrm{GeV}/c$ associated with particles of ${p}_{\ensuremath{\perp}}^{\mathrm{trig}}>4\text{ }\text{ }\mathrm{GeV}/c$ are reconstructed in $pp$ and $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. The associated multiplicity and ${p}_{\ensuremath{\perp}}$ magnitude sum are found to increase from $pp$ to central $\mathrm{Au}+\mathrm{Au}$ collisions. The associated ${p}_{\ensuremath{\perp}}$ distributions, while similar in shape on the nearside, are significantly softened on the awayside in central $\mathrm{Au}+\mathrm{Au}$ relative to $pp$ and not much harder than that of inclusive hadrons. The results, consistent with jet quenching, suggest that the awayside fragments approach equilibration with the medium traversed.
