Left: "exoticity" ($F_{\rm +}$) as function of the cluster energy found with the V2 clusterizer in pp collisions at $\sqrt{s}=13$ TeV using the EMCal high threshold L1 $\gamma$ trigger. The region above the line is populated by exotic clusters. The distributions are normalized to have an integral of unity for each energy bin. Right: comparison of $F_{+}$ probability distributions for measured data (black), projection of the left panel, and simulated (blue) collisions for two different cluster-energy intervals. Each distribution is normalized by the integral of the distribution for $F_{+}< 0.85$.
