Study on Dependence of Diffraction Dissociation Phenomenon in Neutrino Interactions with Nuclei

Only after the introduction of the electron proton accelerator HERA was able to conduct experiments on the diffraction dissociation phenomenon in photo and electro production. We present results on A-dependence of diffraction dissociation (DD) phenomenon in interactions of muonic neutrino with nuclei at various values of momentum transfer. Calculations were done within the two-gluon exchange model by Nikolaev-Zakharov-Zoller (NZZ). Comparison with experimental data obtained in interactions of muonic neutrino with photo emulsion nuclei is carried out. All data are presented as ratio of the DD cross section to the deep inelastic cross section.
