Top: raw associated yield per trigger particle $Y$ (left) as a function of $\Delta \eta$ and $\Delta \varphi$ for pairs of charged particles measured in $\vert \eta \vert < 0.8$ with $5 < p_{\rm T}^{\rm trig} < 6$ GeV/$c$ and $2 < p_{\rm T}^{\rm assoc} < p_{\rm T}^{\rm trig}$ GeV/$c$ in high-multiplicity (0-10%) Pb-Pb collisions at $\snn = 5.02$ TeV, and fit of the distribution (right). Bottom: extracted jet-particle (left) and background (right) yields.
