Title:     Neutron anti-neutron oscillations in a warped extra dimension

Abstract: I will discuss neutron-antineutron oscillations in the
Randall-Sundrum (RS) warped extra dimensional scenario. The RS
model was put forward as a solution to the hierarchy problem
but has also evolved into a model of flavor in the standard
model. Since it is known that proton decay is a problem for
the RS model a natural question is what is the status of
neutron-antineutron oscillation? I will talk about the
calculation of the four dimensional effective coupling
strengths of the relevant operators that induce the
oscillations along with their corresponding enhancements due
to QCD 1-loop running effects. We have shown that the relevant
operators can be geometrically suppressed without fine tuning
to within current experimental limits with a warped down four
dimensional mass scale which can be as low as a fraction of a
TeV.
