The parton model was proposed by Richard Feynman in 1969 [1] for the analysis of proton collisions at high energies. This model assumes that a hadron (such as a proton ) consists of several point formations called partons. The parton model made it possible to explain the results of deep inelastic scattering of electrons by protons [2] . Then, after the discovery of Bjorken's scaling, confirmation of the quark model, and asymptotic freedom in quantum chromodynamics , partons were identified as quarks and gluons .
