Partial-wave amplitudes and multiparticle production

Recursion relations for integrals of amplitudes over the phase space, i.e. for partial wave amplitudes, are introduced. In their simplest form these integrals are proportional to the s-wave amplitudes and represent rigorous lower bounds on the total cross sections. The connection with classical field equations in D dimensions is established. Previous results on multiparticle amplitudes are easi...

Partial wave decomposition of pion and photoproduction amplitudes

Partial wave amplitudes for production and decay of baryon resonances are constructed in the framework of the operator expansion method. The approach is fully relativistically invariant and allow us to perform combined analyses of different reactions imposing directly analyticity and unitarity constraints. All formulas are given explicitly in the form used by the Crystal Barrel collaboration in...

Dips in partial wave amplitudes from final state interactions.

We consider the dip-peak structures in the J=0 partial wave amplitudes for processes γγ → WW and γγ, gg → tt taking into account the corresponding Born term process and the rescattering process where the intermediate state is rescattered through the exchange of Higgs resonance state in the direct channel. Near a direct channel resonance, final state interactions can be important even for relati...

Multiparticle Production and Statistical Analogies

The study of singularities and zeros of the generating functions of multiplicity distributions is advocated. Some hints from well known probability distributions and experimental data are given. The statistical mechanics analogies provoke to look for a signature of phase transitions. The program of further experimental studies of the singularities is formulated. Multiplicity distributions in hi...

Multiparticle Production and Perturbative Qcd

The perturbative quantum chromodynamics (QCD) is quite successful in the description of main features of multiparticle production processes. Ten most appealing characteristics are described in this brief review talk and compared with QCD predictions. The general perturbative QCD approach is demonstrated and its problems are discussed. It is shown that the analytical calculations at the parton l...
