Abstract
We study the single top quark production and decay mechanisms at one-loop level occurring via flavor-changing neutral currents in the Minimal Universal Extra Dimensions (MUED) model. We make a complete study of the model in the Feynman gauge. Especially, we focus on extracting the complete list of 3- and 4-point interactions and determining the mixings among the gauge eigenstates to form the so-called mass eigenstates. Once we have the complete model analyzed, it is implemented via the LanHEP package and transferred to specialized programs such as FeynArts, FormCalc, and LoopTools for automatic calculations. Finally, we explore the MUED predictions for rare top processes in detail and interpret our results.Thesis (M.S.) -- Graduate School of Natural and Applied Sciences. Physics
