Intensity-dependent pion-nucleon coupling and the Wroblewski relation
Abstract
We propose an intensity-dependent pion-nucleon coupling Hamiltonian within a unitary multiparticle-production model of the AABS type in which the pion field 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. The Hamiltonian of our model is expressed linearly in terms of the generators of the SU(1,1) group.
