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.
