$\sigma_{\rm long}^{2}$ as a function of the exoticity parameter $F_{+}$ obtained from V2 clusters with $12< E< 15$ GeV. The distributions are shown for pp collisions at $\sqrt{s}=13$ TeV using the EMCal L1 $\gamma$ (high) trigger at $E^{\rm L1-trig}=9$ GeV (left) and Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV for $0-10$% central collisions.
