Abstract:
Extensions of the Standard Model featuring a warped extra dimension offer a compelling explanation of both the gauge hierarchy problem and the flavor puzzle. In many practical realizations of this idea, the new heavy particles — the Kaluza-Klein excitations of the known fermions and gauge bosons — are too heavy to be produced at the LHC. We show that precision measurements of the production and decay rates of the Higgs boson and of rare flavor-changing processes can provide sensitive indirect probes of these particles. Such processes could therefore provide first hints about the existence of an extra dimension. The direct discovery of the Kaluza-Klein particles may have to await the operation of a super-high energy hadron collider.
