Description
We discuss the equation of state in the confining regime of SU(N)
Yang-Mills theories in (2+1) and (3+1) dimensions.
We show that the results are described very well by
a gas of massive, non-interacting glueballs, provided one assumes
that, in addition to the known particles lighter than the
two-particle threshold, the theory features a physical spectrum
described by an exponentially growing Hagedorn density,
which can be modeled by a bosonic closed-string model.
