Dilaton invading from infinitesimal extra dimension

چکیده
We show that the Wess–Zumino action for spontaneously broken Weyl (or conformal) symmetry, a.k.a dilaton effective action, in even [Formula: see text] dimensions can be obtained from Kaluza–Klein dimensional reduction of Lovelock by taking limit, where is identified with metric extra dimension. The construction gives an explicit form any dimensions.

Large Extra Dimensions from a Small Extra Dimension
Models with extra dimensions have changed our understanding of the hierarchy problem. In general, these models explain the weakness of gravity by diluting gravity in a large bulk volume, or by localizing the graviton away from the standard model. In this paper, we show that the warped geometries necessary for the latter scenario can naturally induce the large volumes necessary for the former. W...
متن کاملConstrained 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 کاملAccelerating Universe from Extra Spatial Dimension
We present a simple higher dimensional FRW type of model where the acceleration is apparently caused by the presence of the extra dimensions. Assuming an ansatz in the form of the deceleration parameter we get a class of solutions some of which shows the desirable feature of dimensional reduction as well as reasonably good physical properties of matter. Interestingly we do not have to invoke an...
متن کاملMultigravity from a discrete extra dimension
Multigravity theories are constructed from the discretization of the extra dimension of five dimensional gravity. Using an ADM decomposition, the discretization is performed while maintaining the four dimensional diffeomorphism invariance on each site. We relate the Goldstone bosons used to realize nonlinearly general covariance in discretized gravity to the shift fields of the higher dimension...
متن کاملInfinitesimal Hartman-Grobman Theorem in Dimension Three.
In this paper we give the main ideas to show that a real analytic vector field in R3 with a singular point at the origin is locally topologically equivalent to its principal part defined through Newton polyhedra under non-degeneracy conditions.
