Flavor physics in the models with warped extra dimension

I will first briefly review the Standard Model and gauge hierarchy problem. Then I will present the Randall-Sundrum model with warped extra dimension, which provides an elegant geometrical solution to the hierarchy problem. The main focus of this thesis will be an analysis of the flavor violation in the models with warped extra dimension. First I will discuss the bounds on the scale of the extra dimension arising from the low energy physics. I will show that there is a tension in the parameter space coming from different low energy observables, and I will also discuss possible ways to relax these bounds. Another interesting feature of the warped models is that they generically predict flavor violation in the Higgs sector. I will discuss low energy flavor constraints on the Higgs mediated flavor violation as well as its signatures at the collider experiments. In the last part of this thesis I will discuss the physics of radion, a scalar degree of freedom of the five dimensional gravity multiplet, and I will show why it has interactions which are generically flavor misaligned leading to the observable flavor violation. This, combined with the fact that radion is likely to be the lightest new physics degree of freedom will lead to the interesting phenomenology both from perspective of collider phenomenology and low energy observables.
