Ultraviolet dependence of Kaluza-Klein effects on electroweak observables
In extensions of the standard model (SM) with d extra dimensions at the TeV scale the virtual exchange of Kaluza-Klein (KK) excitations of the gauge bosons gives contributions that change the SM relations between electroweak observables. These corrections are finite only for d = 1; for d ≥ 2 the infinite tower of KK modes gives a divergent contribution that has to be regularized introducing a c...
متن کاملEffects of SM Kaluza-Klein excitations on electroweak observables
The presence of an extra dimension of size R ≈ TeV−1 introduces a tower of KaluzaKlein gauge boson excitations that affects the standard model (SM) relations between electroweak observables. The mixing of theW and Z bosons with their excitations changes their masses and couplings to fermions. This effect depends on the Higgs field, which may live in the bulk of the extra dimension, on its bound...
متن کاملKaluza - Klein Excitations and Electroweak Symmetry Breaking
We explore the possibility that the Kaluza-Klein graviton states induce electroweak symmetry breaking. We also demonstrate that electroweak symmetry breaking could have a large impact on KK phenomenology. Recently, it has become clear that quantum gravity as described using extra dimensions, and the associated Kaluza-Klein excitations, could have effects at scales far below the measured Planck ...
متن کاملExtra Dimension Kaluza-Klein Excitations and Electroweak Symmetry Breaking
We review the possibilities that the Kaluza-Klein excitations of graviton states induce electroweak symmetry breaking and that electroweak symmetry breaking could have a large impact on KK phenomenology. In one popular approach [1] to extra dimensions with length scales far larger than the inverse Planck mass [2], ordinary particles are confined on a brane (having three spatial dimensions) with...
متن کاملSupersymmetry Effects on High–precision Electroweak Observables
I summarise the virtual effects of the new particles predicted by supersymmetric extensions of the Standard Model on the high–precision electroweak observables measured at LEP/SLC, the Tevatron and CLEO. I will then discuss in some details the two–loop SUSY–QCD corrections to the ρ parameter. Lecture givent at X Escola Jorge André Swieca de Part́ıculas e Campos 7–12 February 1999, Aguas de Lindõ...
