Left: Probability distribution of the $\delta p_{\rm T}$ distribution for random cones with radii of $R = 0.2$ and $R = 0.4$ excluding the 2 leading jets in the EMCal for the 10% most central Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=$ 5.02 TeV. On top of the distributions, the corresponding Gaussian fits for $\delta p_{\rm T}< 0$ are displayed as dashed and dotted lines Right: Comparison of the Gaussian width of the $\delta p_{\rm T}$ distribution as a function of centrality for $R = 0.2$ and $R = 0.4$ in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=$ 5.02 TeV.
