Theoretical studies on more than three spatial dimensions are currently showing a distinct
shift toward the'brane world'picture, in which ordinary matter (with the possible exceptions of …

This chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the
theoretical, phenomenological and experimental issues related to flavor phenomena in the …

Five-dimensional models where the bulk is a slice of AdS have the virtue of solving the
hierarchy problem. The electroweak scale is generated by a “warp” factor of the induced …

We study gravity in backgrounds that are smooth generalizations of the Randall–Sundrum
model, with and without scalar fields. These generalizations include three-branes in higher …

We generalize the mechanism proposed in a previous paper and show that a four-
dimensional relativistic tensor theory of gravitation can be obtained on a delta-function …

Let Θ be the Wigner time reversal operator for spin half and let ϕ be a Weyl spinor. Then, for
a left-transforming ϕ, the construct ζ λ Θ ϕ∗ yields a right-transforming spinor. If instead, ϕ is …

We study five-dimensional solutions to Einstein equations coupled to a scalar field. Bounce-
type solutions for the scalar field are associated with AdS5 spaces with smooth warp …

We argue that the cosmological constant problem can be solved in a braneworld model with
infinite-volume extra dimensions, avoiding no-go arguments applicable to theories that are …

After presenting string-like solutions with a warp factor to Einstein's equations, we study
localization of various spin fields on a string-like defect in a general space–time dimension …
