 Per-trigger yield modification, $I_{\rm AA}$, on the near side(top) and away side(bottom) with trigger $\pi^{0}$ particle at $8< p_{\mathrm{T}}^{\rm trig} < 16~\mathrm{GeV}/c$ for 0-10% Pb-Pb collisions at $\snn=2.76$ TeV. The data from our previous measurement using di-hadron correlations are slightly displaced for better visibility. The bars represent statistical and the boxes systematic uncertainties.
