Two universal extra dimensions and spinless photons at the ILC
We study the ILC phenomenology of (1,0) Kaluza-Klein (KK) modes along two universal extra dimensions compactified on the chiral square. We compute production cross sections of various (1,0) particles at the ILC with √ s = 1 TeV, focusing on decays of KK-leptons and the KK partner of hypercharge gauge boson down to the " spinless photon " which is the lightest KK particle. We contrast this model...
متن کاملAnomalies as a signature of extra dimensions
The anomaly cancellation condition of the Standard Model may be unnatural in theories with extra dimensions as an anomaly of a low-energy 4-dimensional theory can be canceled by an inflow from a bulk. This inflow may give rise to an observable effect at low energies. We analyze several physical models in which this effect exists and estimate constraints on its value, imposed by the modern exper...
متن کاملAccelerating Universe as Window for Extra Dimensions
Homogeneous cosmological solutions are obtained in five dimensional space time assuming equations of state p = kρ and p1 = γρ where p is the isotropic 3 pressure and p1, that for the fifth dimension. Using different values for the constants k and γ many known solutions are rediscovered. Further the current acceleration of the universe has led us to investigate higher dimensional gravity theory,...
متن کاملDark Energy as Evidence for Extra Dimensions
It is argued that fluctuations of quantum fields in four-dimensional space do not give rise to dark energy, but are rather a negligible contribution to dark matter. By (relativistic) dark matter we mean that the relation between pressure and energy density is p = 1 3 u, while dark energy is characterized by p = −u. A possible source of dark energy are the fluctuations in quantum fields, includi...
متن کاملElectroweak Symmetry Breaking as a Consequence of Compact Dimensions
It has been shown recently that the Higgs doublet may be composite, with the left-handed top-bottom doublet and a new right-handed anti-quark as constituents bound by some four-quark operators with non-perturbative coefficients. I show that these operators are naturally induced if there are extra spatial dimensions with a compactification scale in the multi-TeV range. The Higgs compositness is ...
