    "abstract": "We propose an intensity-dependent pion-nucleon coupling Hamiltonian within a\nunitary multiparticle-production model of the Auerbach-\nAvin-Blankenbecler-Sugar (AABS) type in which the pion field is represented by\nthe thermal-density matrix.Using this Hamiltonian, we explain the appearance of\nthe negative-binomial (NB) distribution for pions and the well-known empirical\nrelation, the so-called Wr\\\u0027 oblewski relation, in which the dispersion $D$ of\nthe pion- multiplicity distribution is linearly related to the average\nmultiplicity $\u003cn\u003e$ : $D = A \u003cn\u003e + B$, with the coefficient $A \u003c 1$. The\nHamiltonian of our model is expressed linearly in terms of the generators of\nthe $SU(1,1)$ group.We also find the generating function for the pion field,\nwhich reduces to the generating function of the NB distribution limit $T \\to\n0$.",
