Abstract

We consider the phenomenology of the decay of a Z boson into a photon and a Kaluza–Klein excitation of the graviton in the ADD model. Using LEP data, we obtain an upper bound on the branching ratio corresponding to this process of ∼10-11. We also investigate energy profiles of the process.
