Sažetak
We propose an intensity-dependent pion-nucleon coupling Hamiltonian within a unitary
multiparticle-production model of the Auerbach-Avin-Blankenbecler-Sugar (AABS) type
in which the pion feld is represented by the thermal-density matrix. Using this
Hamiltonian, we explain the appearance of the negative-binomial (NB) distribution
for pions and the well-known empirical relation, the so-called Wroblewski relation,
in which the dispersion D of the pion-multiplicity distribution is linearly related
to the average multiplicity < n > : D = A < n > + B, with the coefficient A<1.
The Hamiltonian of our model is expressed linearly in terms of the generators of the
SU(1,1) group. We also find the generating function for the pion field, which reduces
to the generating function of the NB distribution limit T-0.
