Branes in external field or more about Randall - Sundrum scenario
Fate of branes in external fields is reviewed with emphasis on a spontaneous creation of the Brane World. No negative tension brane is involved. The word " brane " in this talk will stand for a multidimensional relativistic massive film, possibly charged with respect to an n-form (gauge) field. The branes below can be viewed on as the fundamental ones or as effective ones, e.g. domain walls. It...
متن کاملSupersymmetric Randall-Sundrum Scenario
We present the supersymmetric version of the minimal Randall-Sundrum model with two opposite tension branes.
متن کاملRadion Phenomenology in the Randall Sundrum Scenario
Phenomenology of a radion (φ) in the Randall-Sundrum scenario is discussed. The radion couples to the trace of energy momentum tensor of the standard model with a strength suppressed only by a new scale (Λφ) which is an order of the electroweak scale. In particular, the effective coupling of a radion to two gluons is enhanced due to the trace anomaly of QCD. Therefore, its production cross sect...
متن کاملTorsion Constraints in the Randall–Sundrum Scenario
Torsion appears due to fermions coupled to gravity and leads to the strongest particle physics bounds on flat extra dimensions. In this work, we consider torsion constraints in the case of a warped extra dimension with brane and bulk fermions. From current data we obtain a 3σ bound on the TeV–brane mass scale Λπ ≥ 2.2 (10) TeV for the AdS curvature k = 1 (0.01) in (reduced) Planck units. If Dir...
متن کاملCosmology in the Randall-Sundrum Brane World Scenario
The cosmology of the Randall-Sundrum scenario for a positive tension brane in a 5-D Universe with localized gravity has been studied extensively recently. Here we extend it to more general situations. We consider the time-dependent situation where the two sides of the brane are different AdS/Schwarzschild spaces. We show that the expansion rate in these models during inflation could be larger t...
