Randall-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 کاملBrane Tensions and Coupling Constants from within M-Theory
Reviewing the cancellation of local anomalies of M-theory on R × S/Z2 the Yang-Mills coupling constant on the boundaries is rederived. The result is λ = 2(2π)(4πκ) corresponding to η = λ/κ = 256π in the “upstairs” units used by Hořava and Witten and differs from their calculation. It is shown that these values are compatible with the standard membrane and fivebrane tensions derived from the M-t...
متن کاملModuli fields and brane tensions: generalizing the junction conditions
Taking the Randall–Sundrum models as background scenario, we derive generalized Israel–Lanczos–Sen thin-shell junction conditions for systems in which several bulk scalar fields are non-minimally coupled to gravity. We demonstrate that the form of the junction conditions (though arguably not the physics) depends on the choice of frame. We show that generally (in any frame except the Einstein fr...
متن کاملCoupling Constants and Brane Tensions from Anomaly Cancellation in M-theory
The theory of eleven dimensional supergravity on R × S/Z2 with super Yang-Mills theory on the boundaries is reconsidered. We analyse the general solution of the modified Bianchi identity for the four-form field strength using the equations of motion for the three-form and find that the four-form field strength has a unique value on the boundaries of R × S/Z2. Considering the local supersymmetry...
متن کاملSurface tensions
With so many fish stocks under pressure, increasing catch levels for one population by 30 per cent might appear catastrophic. But European fishing ministers believe such a move might help tackle two problems. Fishermen in the North Sea will be able to catch more cod this year, but cod fisheries elsewhere around Europe will be further restricted. EU ministers agreed late last month the fish quot...
