Top panels: fully corrected \PbPb{} $\DeltaR^{\rm WTA-Standard}/R$ (left), and $\DeltaR^{\rm WTA-SD}/R$ with $(\zcut=0.2,\beta=0)$ (right) distributions in the \pTchjet{} interval $[100,140]$ \GeVc Central and bottom panels: measured $\PbPb (R=0.4)/\PbPb(R=0.2)$ ratio in black, as well as predictions from a selection of jet quenching models.
