Abstract

In this research, the cross sections of the leptonic interactions is calculated using the two approximations: Fermi approximation and the standard model of particle physics. The differences between the two approximations was found. The cross sections in Fermi approximation is proportional to the total energy  in center mass system (c.m.s), while in the approximation of the standard model, the cross sections is inversely proportional to the total energy. We also found at high energy that, the Fermi approximation break down and we cannot trust calculations of the cross sections with this approximations. Therefore, it is better to use the standard model approximation when dealing with higher energies. Furthermore we found that the cross section of electron antineutrino scattering on electron is equal to one-third of the cross section of electron neutrino scattering on electron.
