Track: Quark Flavour Violation: SM and Beyond

Content

While the Randall-Sundrum scenario provides a solution to both the gauge and fermion hierarchy problems, stringent constraints from flavour physics and EW precision data have been shown to force the KK scale to about 20-30 TeV. This can be ameliorated, to some extent, by modifications to the background, and conversely, flavour observables can probe the geometry of the extra dimension. Of particular interest are flavour changing interactions that are mediated by Kaluza Klein modes of the neutral gauge bosons, since these provide tree level corrections to processes which are loop suppressed in the Standard Model. I will present an approach to calculating two-point correlation functions of the KK bosons in a way which is easily adaptable to modifications of the gravitational background. I will then present results calculated using these methods with selected warped metrics, for observables related to \Delta F=1 and \Delta F=2 processes. I will conclude with comments on their implications.
