Effects of Baluza-Klein excitations on g(mu)-2 - art. no. 116006

An analysis of the effects associated with the Kaluza-Klein excitations of the photon and of the W and Z bosons on g(mu)-2 for d number of extra dimen sions with large radius compactifications is given. The Kaluza-Klein effect s on g(mu)-2 are found to be very sensitive to the number of extra dimensio ns. For models where the quark-lepton generations live on the four-dimensio nal wall, it is shown that when the constraints from the Kaluza-Klein corre ctions to the Fermi constant are included, the effects of the Kaluza-Klein excitations to g(mu)-2 become too small to be observable. A model which eva des Kaluza-Klein corrections to the muon decay mu-->e<(nu)over bar>(e)nu(mu ), without suppression of their effects on g(mu)-2 is discussed. [S0556-282 1(99)03021-0].
