Abstract
Hawking has shown that event-horizon-containing classical soliton (black-hole) solutions of Einstein's equation radiate all species of particles with a thermal spectrum, the temperature being defined in terms of surface gracity. For a spinless soliton, the temperature is inversely proportional to the radius of its event-horizon. Assuming that there exists a fundamental strongly-interacting (massive) spin-2 field satisfying an Einstein-like equation with a strong coupling parameter, we propose to identify temperature in hadronic physics with strong surface gravity effects. The existence of black-body solitonic solutions for such an equation may then explain the thermal spectrum in E T observed in high-energy collisions.
