Particle production in high energy collisions
A short historical review is made of charged particle production at high energy proton synchrotrons and at pp and pp colliders. The review concerns mainly low pt processes, including diffraction processes, and fragmentation of nuclei in nucleus-nucleus collisions. A short recollection is made of the first studies of high pt processes. Conclusions and perspectives follow.
متن کاملPartons and QCD in high - energy polarized pp collisions
We present and use a technique for implementing in a fast way, and without any approximations, higher-order calculations of partonic cross sections into global analyses of parton distribution functions. The approach, which is set up in Mellin-moment space, is particularly suited for analyses of future data from polarized proton-proton collisions at RHIC, but not limited to this case. We also br...
متن کاملCharge and Isospin Fluctuations in High Energy pp-Collisions
Charge and isospin event-by-event fluctuations in high-energy pp-collisions are predicted within the Unitary Eikonal Model, in particular the fluctuation patterns of the ratios of charged-to-charged and neutral-to-charged pions. These fluctuations are found to be sensitive to the presence of unstable resonances, such as ρ and ω mesons. We predict that the charge-fluctuation observable DUEM shou...
متن کاملDiffractive dissociation and eikonalization in high energy pp and pp-bar collisions.
We show that eikonal corrections imposed on diffraction dissociation processes calculated in the triple Regge limit, produce a radical change in the energy dependence of the predicted cross section. The induced correction is shown to be in general agreement with the recent Tevatron experimental data. ∗ a) On leave from Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg † b) On leave...
متن کاملSqueezed States and Particle Production in High Energy Collisions
Using the ‘quantum optical approach’ we propose a model of multiplicity distributions in high energy collisions based on squeezed coherent states. We show that the k-mode squeezed coherent state is the most general one in describing hadronic mulitiplicity distributions in particle collision processes, describing not only pp collisions but e+e−, νp and diffractive collisions as well. The reason ...
