The recently suggested interpretation P. Castorina, D. Kharzeev, and H. Satz, [Eur. Phys. J. C 52, 187 (2007).] of the universal hadronic freeze-out temperature T{sub f} ({approx_equal}170 MeV)--found for all high-energy scattering processes that produce hadrons e{sup +}e{sup -}, pp, pp, {pi}p, etc., and NN{sup '} (heavy-ion collisions)--as an Unruh temperature triggers here the search for the gravitational black hole (BH) that in its near-horizon approximation better simulates this hadronic phenomenon. To identify such a BH we begin our gravity-gauge theory phenomenologies matching by asking the question: which BH behind that Rindler horizon could reproduce the experimental behavior of T{sub f}({radical}(s)) in NN{sup '}, where {radical}(s) is the collision energy? Provided certain natural assumptions hold, we show that the exact string BH turns out to be the best candidate (as it fits the available data on T{sub f}({radical}(s))) and that its limiting case, the Witten BH, is the unique candidate to explain the constant T{sub f} for all elementary scattering processes at large energy. We also are able to propose an effective description of the screening of the hadronic string tension {sigma}({mu}{sub b}) due to the baryon density effects on T{sub f}.
