In the last five years ample evidence has been found supporting the idea that the quark-parton structure of hadrons is relevant for multiple production in soft hadronic collisions. Starting from the experimental foundations, we compare the most successful models applying this idea. Implications are discussed on special type reactions like diffraction dissociation and collisions on nuclei, and the models are confronted with recent data leading to new insight and modifications. Relative yields of particles in the central region may be understood as reflecting their valence quark structure in the framework of quark combinatorics, and the comparison of the valence structure of initial and final hadrons allows us to understand yields in the fragmentation regions. From the structure functions of initial hadrons and/or the fragmentation functions of (di)quarks into final hadrons as seen in deep inelastic lepton-hadron or e+ecollisions, one can deduce the shape of fragmentation spectra in soft hadronic collisions. However, hadronic collisions also prove a very rich independent source of information on parton structure. Work to be done on the theoretical side is on a solid foundation of the two successful pictures of quark fragmentation and quark recombination as well as on an explanation of their apparent complementarity. On the experimental side, apart from further results from the pp collider, high statistics is needed on hydrogen and on heavier nuclei at Plab > 200 GeV/c in particular from strange beams.

“…Guided by the experimental results on the production of the latter in pp collisions (see, e.g., Fig. 3 in [35]), we assume that the glob multiplicity at 10.5 GeV/c is three times smaller than that at 70 GeV/c. In this way we mimic the threshold effect which must exist in the production of globs in low-energy collisions.…”

Consistency of data on soft photon production in hadronic interactions

The glob model of Lichard and Van Hove and the modified soft annihilation model (MSAM) of Lichard and Thompson are used as a phenomenological tool for relating results from various experiments on soft photon production in high energy collisions. The total phenomenological expectation is composed of contributions from classical bremsstrahlung, the soft annihilation model and the glob model. The empirical excess above the background from hadronic decays at very small longitudinal momenta of photons is well reproduced, as well as that for transverse momenta p T > ∼ 10 MeV/c. Some data do not require the glob model and MSAM components in the phenomenological mixture, but do not exclude them. On the basis of consistency of all data with the total theoretical expectation we argue that the results of all experiments are mutually consistent. The models are unable to describe the excess of ultrasoft photons (p T < ∼ 10 MeV/c), seen by some, but not all, experiments. This may indicate an as yet unknown projectile-mass-dependent production mechanism. Possible relations of soft photon production to other phenomena are discussed. A simple-to-use, but physically equivalent version of the glob model is developed, which enables an easy check of presented results.

A compilation of fits to the low pT hadron distributions is presented. The universality of the distributions is examined. The pT distributians of direct pions and resonances in the reaction pp → 2π+2π−π0 at 5.7 GeV/c are fitted separately. Indications are found that up to ISR energies there are three types oflow pT inclusive hadron distributions in hadron‐hadron interactions. The inclusive pT distributions of different particles are divided into these three groups according to the particle mass.
