Notes: We define a minimal model with Universal Extra Dimensions, and
begin to study its phenomenology. The collider signals of the first KK level are
surprisingly similar to those of a supersymmetric model with a nearly degenerate
superpartner spectrum. The lightest KK particle (LKP) is neutral and stable
because of KK-parity. KK excitations cascade decay to the LKP yielding missing
energy signatures with relatively soft jets and leptons. Level 2 KK modes may
also be probed via their KK number violating decays to Standard Model particles.
In either case we provide initial estimates for the discovery potential of the
Tevatron and the LHC.
Event Selection: 4 leptons + MET; MET + n>2 jets w/ and w/o taking the
invariant mass of leading jets
Conclusions: 4 leptons + MET is "gold-plated", taking invariant mass of
leading jets in MET+n>2 jets can help discover KK=2 modes, thus distinguishing
between ED and SUSY.
