Abstract
We studied the electronpositron annihilation process in which it creates muon and antimuon and the phenomenon of Compton scattering of a photon o� an electron. The differential scattering crosssections are calculated for electronpositron annihilation process and that for Compton scattering also. Here we calculated the unpolarized scattering crosssections. The differential scattering crosssections are found explicitly in the centreofmass frame. But all such process have higher order corrections also, which contain loops. Here we will also describe the correction to electron scattering which comes from the presences of an additional virtual photon. The higher order correction also needs Feynman Diagrams using which we can do the higher order calculation. Here we wrote a Mathematica code which will generate one loop and two loop connected diagrams for two point function in �3 theory and �4 theory respectively.
