More about *Kaluza-Klein* Regularization

, 2001

"... We study the so-called “Kaluza-Klein regularization”. We calculate one-loop corrections to the Higgs mass due to Kaluza-Klein modes explicitly in a model with SUSY breaking mass splitting between bosonic and fermionic modes. We perform the proper time cutoff at 1/Λ2 and the KK level truncation at . ..."

Hidden photons with *Kaluza-Klein* towers

, 2014

"... One of the simplest extensions of the Standard Model (SM) is an extra U(1) gauge group under which SM matter does not carry any charge. The associated boson – the hidden photon – then interacts via kinetic mixing with the ordinary photon. Such hidden photons arise naturally in UV extensions such as ..."

We investigate the constraint on the split fermions in extra dimensions by considering the universality of W leptonic decays W → liνi, the lepton decays li → ljνi¯νj, the lepton flavor violating process li → ¯ljlklh and the li → ljγ transition where li = e,µ or τ.

*Kaluza-Klein* Excitations of W and Z at the LHC?

, 2001

"... Deviations from standard electroweak physics arise in the framework of a Randall-Sundrum model, with matter and gauge fields in the bulk and the Higgs field localized on the TeV brane. We focus in particular on modifications associated with the weak mixing angle. Comparison with the electroweak prec ..."

1 Intrinsic Spin and the *Kaluza-Klein* Fifth Dimension

"... Kaluza-Klein Theories provide a compelling unification of classical gravitation with classical electrodynamics, but have long been plagued by the perceived absence of physical evidence of a compactified, hypercylindrical, spacelike fifth dimension. We examine the possibility that this fifth dimensio ..."

Collider Implications of *Kaluza-Klein* Excitations of the Electroweak Gauge *Bosons*

, 2001

"... It is possible for the SM fields to propagate into one or more large extra compact dimensions. Such fields have associated KK excitations that produce additional contributions to the SM processes. We calculate the effects that these KK excitations have on cross sections for e + e − collider processe ..."
