Testing the nature of Kaluza-Klein excitations at future lepton colliders
Testing the nature of Kaluza-Klein excitations at future lepton colliders
With one extra dimension, current high precision electroweak data constrain the masses of the first Kaluza-Klein (KK) excitations of the standard model gauge fields to lie above $\ensuremath{\simeq}4$ TeV. States with masses not much larger than this should be observable at the CERN LHC. However, even for first excitation masses …
