  A Hamiltonian eikonal model for the multiple production in high energy hadron
hadron collisions is presented and worked out in the aim of providing a simple
frame for many different observables of these processes. The Hamiltonian
formulation ensures that it has the unitarity built in by construction and the
eikonal approximation makes easier the discussion of the possible spacial
inhomogeneities of the hadrons. The experimental data which are examined are
the inelastic cross section and the single and double inclusive cross sections.
