Abstract: | Multihadron production in high energy collisions, from e+e-
annihilation to heavy ion interactions, shows remarkable thermal
behaviour, specified by a universal “Hagedorn” temperature.
We argue that this hadronic radiation is formed by tunneling
through the event horizon of colour confinement, i.e., that it
is the QCD counterpart of Hawking-Unruh radiation from black holes.
It is shown to be emitted at a universal temperature TH ≃
(σ/2 π)1/2, where σ denotes the string tension.
Since the event horizon does not allow information transfer,
the radiation is thermal “at birth”. |
