Constrained Standard Model from Extra Dimension
A five dimensional supersymmetric model is constructed which reduces to the one Higgs-doublet standard model at low energies. The radiative correction to the Higgs potential is finite and calculable, allowing the Higgs mass prediction of 127± 8 GeV. The physical reasons for this finiteness are discussed in detail. The masses of the superparticles and the Kaluza-Klein excitations are also predic...
متن کاملA Constrained Standard Model from a Compact Extra Dimension
A SU(3)× SU(2)×U(1) supersymmetric theory is constructed with a TeV sized extra dimension compactified on the orbifold S/(Z2 × Z ′ 2). The compactification breaks supersymmetry leaving a set of zero modes which correspond precisely to the states of the 1 Higgs doublet standard model. Supersymmetric Yukawa interactions are localized at orbifold fixed points. The top quark hypermultiplet radiativ...
متن کاملThe Excited Scalars of the Universal Extra Dimension Model
In the minimal Universal Extra Dimension (mUED) model, there are four physical scalar particles at the n = 1 level, two charged and two neutral. Due to the almost degenerate nature of the spectrum, the detection of these scalars is a major challenge, perhaps the greatest experimental challenge if UED-type new physics is observed at the Large Hadron Collider (LHC). We explore the possibility of ...
متن کاملExclusive B → K 1 l + l − decay in model with single universal extra dimension
Decay rate and forward-backward asymmetries in B → K1ll , K1 is the axial vector meson, are calculated in the universal extra dimension (UED) model. The dependence of these physical quantities on the compactification radius R, the only unknown paramter in UED model, is studied and it is shown that zero of forward-backward asymmetry is sensitive to the UED model, therefore they can be very usefu...
متن کاملOne universal extra dimension in Pythia
The Universal Extra Dimensions model has been implemented in the PYTHIA generator from version 6.4.18 onwards, in its minimal formulation with one TeV sized extra dimension. The additional possibility of gravity-mediated decays, through a variable number of eV sized extra dimensions into which only gravity extends, is also available. The implementation covers the lowest lying Kaluza-Klein (KK) ...
