Abstract
We derive a partition function for the Lund fragmentation
model and compare it with that of a classical gas. For a fixed
rapidity ``volume'' this partition function corresponds to a
multiplicity distribution which is very close to a binomial
distribution. We compare our results with the multiplicity
distributions obtained from the JETSET Monte Carlo for several
scenarios. Firstly, for the fragmentation vertices of the Lund
string. Secondly, for the final state particles both with and without
decays.
