Type IIB String Theory, S-Duality, and Generalized Cohomology
Igor Kriz, Hisham Sati
In the presence of background Neveu-Schwarz flux, the description of the Ramond-Ramond fields of type IIB string theory using twisted K-theory is not compatible with S-duality. We…
Quantum Discontinuity for Massive Spin 3/2 with a Lambda Term
M. J. Duff, James T. Liu, H. Sati
We show that the recently demonstrated absence of the van Dam-Veltman-Zakharov discontinuity for massive spin 3/2 with a Lambda term is an artifact of the tree level approximation,…
Complementarity of the Maldacena and Karch-Randall Pictures
M. J. Duff, James T. Liu, H. Sati
We perform a one-loop test of the holographic interpretation of the Karch-Randall model, whereby a massive graviton appears on an AdS_4 brane in an AdS_5 bulk. Within the AdS/CFT f…
Quantum M^2 -> 2Lambda/3 discontinuity for massive gravity with a Lambda term
M. J. Duff, James T. Liu, H. Sati
In a previous paper we showed that the absence of the van Dam-Veltman-Zakharov discontinuity as M^2 -> 0 for massive spin-2 with a Lambda term is an artifact of the tree approximat…
Quantum discontinuity between zero and infinitesimal graviton mass with a Lambda term
F. A. Dilkes, M. J. Duff, James T. Liu +1
We show that the recently demonstrated absence of the usual discontinuity for massive spin 2 with a Lambda term is an artifact of the tree approximation, and that the discontinuity…
Breathing mode compactifications and supersymmetry of the brane-world
James T. Liu, H. Sati
It has recently been shown that the Randall-Sundrum brane-world may be obtained from an appropriate doubled D3-brane configuration in type IIB theory. This corresponds, in five dim…
