The Standard Model and Electron Vertex Correction.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
In this thesis we have started by developing the theory for the electroweak Standard Model. A prerequisite for this purpose is a knowledge of gauge theory. For obtaining the Standard Model Lagrangian which describes the entire electroweak SM and the theory in the form of an equation, we need to develop ideas on spontaneous symmetry breaking and Higgs mechanism which will lead to the generation of masses for the gauge bosons and fermions. This is the first part of my thesis. In the second part, we have moved on to radiative corrections which acts as a technique for the verification of QED and the Standard Model. We have started by calculating the amplitude of a scattering process depicted by the Feynman diagram which led us to the calculation of g-factor for electron-scattering in a static vector potential. Then, we have calculated the one-loop contribution to the electron vertex function which has acted as a correction to the g-factor value calculated previously.
