Randall-Sundrum and strings
We investigate stringy excitations in Randall-Sundrum effective theories for electroweak symmetry breaking arising from embedding in string theory. RS is dual to a confining gauge theory, which we expect to have “QCD strings,” or color flux tubes. Stringy constructions of RS-like theories allow us to investigate the mass of these string states, which typically grows with a small fractional powe...
متن کاملRandall-Sundrum Brane Tensions
We show that the singular sources in the energy-momentum tensor for the RandallSundrum brane world, viewed as a solution of type IIB supergravity, are composed of two elements. One of these is a D3-brane source with tension opposite in sign to the RS tension in five dimensions; the other arises from patching two regions of flat ten-dimensional spacetime. This resolves an apparent discrepancy be...
متن کاملSupersymmetric Randall-Sundrum Scenario
We present the supersymmetric version of the minimal Randall-Sundrum model with two opposite tension branes.
متن کاملRandall-Sundrum with AdS(7)
In the same sense that AdS5 warped geometries arise naturally from Type IIB string theory with stacks of D3 branes, AdS7 warped geometries arise naturally from M theory with stacks of M5 branes. We compactify two spatial dimensions of AdS7 to get AdS5 ×Σ 2, where Σ2 is e.g. a torus T 2 or a sphere S2. The metric for Σ inherits the same warp factor as appears in the AdS5. Bulk fields generically...
متن کاملCosmology of Randall-sundrum Models∗
For past two years, many particle physicists and cosmologists were excited by the development of two ideas, the brane world and the warped extra dimensions, both of which are based on the existence of extra dimensions. The basic idea of the brane world is that standard model particles are localized on a (3+1)-dimensional brane (or a set of branes) embedded in a higher dimensional spacetime, whi...
