Query: Multi-State Dark Matter from Spherical Extra Dimensions   We demonstrate a new model which uses an ADD type braneworld scenario to
produce a multi-state theory of dark matter. Compactification of the extra
dimensions onto a sphere leads to the association of a single complex scalar in
the bulk with multiple Kaluza-Klein towers in an effective four-dimensional
theory. A mutually interacting multi-state theory of dark matter arises
naturally within which the dark matter states are identified with the lightest
Kaluza-Klein particles of fixed magnetic quantum number. These states are
protected from decay by a combination of a global U(1) symmetry and the
continuous rotational symmetry about the polar axis of the spherical geometry.
We briefly discuss the relic abundance calculation and investigate the
spin-independent elastic scattering off nucleons of the lightest and
next-to-lightest dark matter states.
