An Sl(3,R) multiplet of 8-dimensional type II supergravity theories and the gauged supergravity inside

N. Alonso-Alberca, P. Meessen, T. Ortin

The so-called ``massive 11-dimensional supergravity'' theory gives, for one Killing vector, Romans' massive 10-dimensional supergravity in 10 dimensions, for two Killing vectors an…

Non-Semisimple Gaugings of D=5 N=8 Supergravity

Laura Andrianopoli, Francesco Cordaro, Pietro Fre' +1

The recent construction of the non-semisimple gaugings of maximal D=5 supergravity is reported here. This construction is worked out in the so-called rheonomic approach, based on F…

Orbifold boundary states from Cardy's condition

M. Billo', B. Craps, F. Roose

Boundary states for D-branes at orbifold fixed points are constructed in close analogy with Cardy's derivation of consistent boundary states in RCFT. Comments are made on the inter…

Symmetries of string, M and F-theories

Eric Bergshoeff, Antoine Van Proeyen

The d=10 type II string theories, d=11 M-theory and d=12 F-theory have the same symmetry group. It can be viewed either as a subgroup of a conformal group OSp(1|64) or as a contrac…

Antifield BRST quantization of duality-symmetric Maxwell theory

Xavier Bekaert, Sorin Cucu

We perform the antifield BRST quantization of duality-symmetric Maxwell theory and show explicitly the quantum equivalence of the different formulations (covariant and non-covarian…

Non-Semisimple Gaugings of D=5 N=8 Supergravity and FDA.s

L. Andrianopoli, F. Cordaro, P. Fre' +1

We reformulate maximal D=5 supergravity in the consistent approach uniquely based on Free Differential Algebras and the solution of their Bianchi identities (= rheonomic method). I…

Half-Integer Winding Number Solutions to the Landau-Ginzburg-Higgs Equations and Instability of the Abrikosov-Nielsen-Olesen Vortex

Jan Govaerts

New solutions to the abelian U(1) Higgs model, corresponding to vortices of integer and half-integer winding number bound onto the edges of domain walls and possibly surrounded by…

Isometries in anti-de Sitter and Conformal Superspaces

P. Claus, J. Rahmfeld, H. Robins +2

We derive explicit forms for the superisometries of a wide class of supercoset manifolds, including those with fermionic generators in the stability group. We apply the results to…

Supersymmetry in Singular Spaces

Eric Bergshoeff, Renata Kallosh, Antoine Van Proeyen

We develop the concept of supersymmetry in singular spaces, apply it in an example for 3-branes in D=5 and comment on 8-branes in D=10. The new construction has an interpretation t…

Non abelian N=2 supersymmetric Born Infeld action

A. Refolli, N. Terzi, D. Zanon

We present a N=2 supersymmetric action for the Born Infeld theory in the non abelian case. We quantize the theory in N=1 superspace and compute divergences at one-loop. The result…

Superconformal Symmetry, Supergravity and Cosmology

Renata Kallosh, Lev Kofman, Andrei Linde +1

We introduce the general N=1 gauge theory superconformally coupled to supergravity. The theory has local SU(2,2|1) symmetry and no dimensional parameters. The superconformal origin…

More on correlators and contact terms in {\cal N}=4 SYM at order g^4

S. Penati, A. Santambrogio, D. Zanon

We compute two-point functions of chiral operators Tr(Φ^k) for any k, in {\cal N}=4 supersymmetric SU(N) Yang-Mills theory. We find that up to the order g^4 the perturbative correc…

The Tachyon Potential in Witten's Superstring Field Theory

Pieter-Jan De Smet, Joris Raeymaekers

We study the tachyon potential in the NS sector of Witten's cubic superstring field theory. In this theory, the pure tachyon contribution to the potential has no minimum. We find t…

The many faces of OSp(1|32)

Eric Bergshoeff, Antoine Van Proeyen

We show that the complete superalgebra of symmetries, including central charges, that underlies F-theories, M-theories and type II string theories in dimensions 12, 11 and 10 of va…

Embedding Branes in Flat Two-time Spaces

L. Andrianopoli, M. Derix, G. W. Gibbons +3

We show how non-near horizon, non-dilatonic -brane theories can be obtained from two embedding constraints in a flat higher dimensional space with 2 time directions. In particul…

Level Four Approximation to the Tachyon Potential in Superstring Field Theory

Pieter-Jan De Smet, Joris Raeymaekers

We compute the tachyon potential to level 4 in NS superstring field theory. We obtain 89% of the conjectured vacuum energy.

TASI lectures on the Holographic Principle

Daniela Bigatti, Leonard Susskind

These TASI lectures review the Holographic principle. The first lecture describes the puzzle of black hole information loss that led to the idea of Black Hole Complementarity and s…
