In this review we collect, for the first time in one paper, old and newresults and future perspectives of the research line that uses hadronproduction, in high-energy scattering processes, to experimentally probefundamental questions of quantum gravity. The key observations, that ignitedthe link between the two arenas, are the so-called ``color-event horizon'' ofquantum chromodynamics, and the enormous (de)accelerations involved in suchscattering processes: both phenomena point to the Unruh (and related Hawking)type of effects. After the first pioneering investigations of this, suchresearch went on and on, including studies of the horizon entropy and other``black-hole thermodynamical'' behaviors, which incidentally are also thefrontier of the analog gravity research itself. It is stressed in variousplaces here that the \textit{trait d'union} between the two phenomenologies isthat in both scenarios, hadron physics and black hole physics, ``thermal''behaviors are more easily understood not as due to real thermalizationprocesses (sometimes just impossible, given the small number of particlesinvolved), but rather to a stochastic/quantum entanglement nature of suchtemperature. Finally, other aspects, such as the self-critical organizations ofhadronic matter and of black-holes, have been recently investigated. Theresults of those investigations are also summarized and commented upon here. Asa general remark, this research line shows that indeed we can probe quantumgravity theoretical constructions with analog systems that are not confined tobelong only to the condensed matter arena. This is as it must be.
