Component Actions from Curved Superspace: Normal Coordinates and Ectoplasm
S. James Gates, Marcus T. Grisaru, Marcia E. Knutt-Wehlau +1
We give efficient superspace methods for deriving component actions for supergravity coupled to matter. One method uses normal coordinates to covariantly expand the superfield acti…
Supergravity from a Massive Superparticle and the Simplest Super Black Hole
Marcia E. Knutt-Wehlau, R. B. Mann
We describe in superspace a theory of a massive superparticle coupled to a version of two dimensional N=1 dilaton supergravity. The (1+1) dimensional supergravity is generated by t…
Tailoring T-Duality Beyond the First Loop
Nemanja Kaloper, Krzysztof A. Meissner
In this article we review a recent calculation of the two-loop -model corrections to the T-duality map in string theory. Using the effective action approach, and focusing on bac…
Fixing the Dilaton with Asymptotically Expensive Physics?
C. P. Burgess, A. de la Macorra, I. Maksymyk +1
We propose a general mechanism for stabilizing the dilaton against runaway to weak coupling. The method is based on features of the effective superpotential which arise for supersy…
Duality Beyond the First Loop
Nemanja Kaloper, Krzysztof Meissner
In this article we give a calculation of the two-loop -model corrections to the T-duality map in string theory. We use the effective action approach, and analyze two-loop correc…
The Octonionic Membrane
M. J. Duff, J. M. Evans, R. R. Khuri +2
We generalize the supermembrane solution of D=11 supergravity by permitting the 4-form to be either self-dual or anti-self-dual in the eight dimensions transverse to the membra…
