Classicalizing theories are characterized by a rapid growth of the scatteringcross section. This growth converts these sort of theories in interestingprobes for ultra-high energy experiments even at relatively low luminosity,such as cosmic rays or Plasma Wakefield accelerators. The microscopic reasonbehind this growth is the production of N-particle states, classicalons, thatrepresent self-sustained lumps of soft Bosons. For spin-2 theories this is thequantum portrait of what in the classical limit are known as black holes. Weemphasize the importance of this quantum picture which liberates us from theartifacts of the classical geometric limit and allows to scan a much widerlandscape of experimentally-interesting quantum theories. We identify aphenomenologically-viable class of spin-2 theories for which the growth ofclassicalon production cross section can be as efficient as to compete with QCDcross section already at 100 TeV energy, signaling production of quantum blackholes with graviton occupation number of order 10^4.
