Abstract: Experimental data from literature has been used to evaluate accurately the cross – section from electron positron annihilation into muon pairs via photon exchange. Cross – section for the same process via Z0 boson exchange was evaluated separately, after which the two amplitudes were summed together and their cross – section evaluated again. The center of mass energies ranging from 2GeV up to and above the Z0 peak were used to study the behavior of the cross – sections at each stage. The three results were compared to observe the effect of the interference between photon/Z0 boson on the center of mass energy dependent of the process.Abstract: Experimental data from literature has been used to evaluate accurately the cross – section from electron positron annihilation into muon pairs via photon exchange.
