Modelling of exclusive parton distributions and long-range rapidity
correlations for pp collisions at the LHC energy    [PDF]

V. Kovalenko

Soft pp interactions are considered in the framework of phenomenological model with color strings formation. Under the assumption that elementary collision is realized as interaction of two color dipoles for the parameters fixing the total inelastic cross section and multiplicity of the charged particles are estimated. The special attention is given to modeling of exclusive parton distributions taking into account the energy conservation and fixing of mass center that is necessary for the description of correlations, corresponding Monte-Carlo procedures are developed for arbitrary number of partons in a hadron. The string fusion algorithm in a cross-section plane is developed taking into account the finite rapidity width of strings. In this framework the influence of string fusion effects on long-range correlations of charged particles estimated. The proposed algorithms are planned to use for studying of heavy ion collisions.
