Abstract
A statistical model for the production of multibody hadronic states by annihilation is discussed. We associate the secondary hadron momentum distributions for colliding-beam processes with the exponentially failling transverse-momentum distributions in hadron-hadron collisions. The consequence of this picture is that at high energies hadron multiplicity rises linearly with c.m. energy, unlike the behavior for the multiplicity of secondaries in hadron-hadron collisions. If the total annihilation cross section is assumed to have a power falloff , the -pion cross sections follow a Poisson distribution with the most probable multiplicity and MeV. An alternative statistical model based on jets is also briefly discussed. The storage rings now being constructed or envisaged should easily distinguish between the various possibilities.
