Nucleus-nucleus interactions at high energies (models and experiments)
- Igor Lokhtin ()
Description
The section will consider contributions on A-A-interactions in Cosmic Rays. Predictions of models and their comparison with experimental results will be reviewed.
The presence of antinuclei in cosmic rays remains one of the most intriguing questions of modern physics, with several ongoing or planned experiments looking for traces of antinuclei in space near Earth. An observation of antideuteron or antihelium nuclei in cosmic rays would most probably mean a breakthrough in searches for "new physics", as the antinuclei production from ordinary collisions...
CMS measurements of inelastic diffraction are reviewed. Agreement of newly
obtained results on diffraction in pPb collisions in parallel with
previously obtained results on diffraction in pp collisions with
generators, in particularly with cosmis ray generators, is discussed.
I discuss the physics content of the QGSJET-III model,paying a particular attention to the treatment of higher twist and color fluctuation effects. The consequences for the energy dependence of both interaction cross sections and particle production will be analyzed. Further, the implementation of the pion exchange mechanism will be described, concentrating on its relevance to the...
Currently, EPOS-LHC is the public EPOS version, heavily used by experimental groups in high energy and cosmic ray physics. It is based on an S-matrix approach, being the ideal framework for multiple scattering in small systems. However, factorization and binary scaling does not come for free, it is a very complex issue, and in the current model it is simply not properly done. Another topic...
Program CORSIKA is the unique and the most common tool for Monte-Carlo simulation of the formation and development of extensive air showers. CORSIKA offers the user a set of hadronic interactions models for both high and low energies, leaving the choice of the model to the user. Thus the comparison of these models is of particular interest.
In the work, four CORSIKA models for high energy...
