Higgs Boson Decay to Two Photons : Probing the Standard Model

The Higgs to Two Photon decay channel is analyzed to one-loop in the Feynman gauge. Triangle loop processes are evaluated using dimensional regularization due to divergent integrals. The build up to Higgs physics is given by way of gauge theories in the Standard Model where we can then introduce the Higgs field. After evaluation of the Higgs di-photon channel, we explore questions of non-perturbative approaches to these calculations, higher order precision calculations, and probing ideas beyong the Standard Model
