description: The topic of this graduate qualification work is "Calculation of deep inelastic electron-proton scattering in the framework of the quark-diquark model". The thesis is devoted to the implemenation of the quark-diquark model in the calculation of deep inelastic electron-proton scattering cross sections. Problems solved in the course of the study: 1. Study of existing mathematical models to describe deep inelastic collisions. 2. Study of the quark-diquark model of baryons. 3. Calculation of deep inelastic electron-proton interaction cross sections in different models. 4. Analysis of the results and modernization of existing calculation methods by introducing a diquark. The work was carried out at the Department of Atomic Nucleus and Elementary Particle Physics at the Higher School of Physics, SPbPU, where the theoretical material was collected. The deep inelastic electron-proton scattering cross sections were calculated in the quark-diquark model at energy âs = 7.2 GeV in the transmitted momentum interval from 1 to 10 GeV^2 and in the Bjorken variable interval from 0.059 to 0.348. A comparison between the experimental results of the HERMES collation and those calculated by means of software packages is presented. The analysis of the experimental data led to the conclusion that the introduction of diquark can improve the approximation of the experimental results.
