Nuclear attenuation of high energy multi-hadron systems in the string model
Nuclear attenuation of the multi-hadron systems in the string model is
considered. The improved two-scale model with set of parameters obtained
recently for the single hadron attenuation is used for calculation of the
multiplicity ratios of the one-, two- and three-hadron systems electroproduced
on nuclear and deuterium targets. The comparison of the features of the one-,
two- and three-hadron systems is performed. The predictions of the model for
multiplicity ratios of multi-hadron systems as functions of different
convenient variables are presented.Comment: 7 pages, 6 figure
Simple parameterization of nuclear attenuation data
Based on the nuclear attenuation data obtained by the HERMES experiment on
nitrogen and krypton nuclei, it is shown that the nuclear attenuation
can be parametrised in a form of a linear polynomial + , where is the formation time, which depends on the energy of the
virtual photon and fraction of that energy carried by the final
hadron. Three widely known parameterizations for were used for the
performed fit. The fit parameters and do not depend on
