Aspects of spinorial geometry
U. Gran, J. Gutowski, G. Papadopoulos +1
We review some aspects of the spinorial geometry approach to the classification of supersymmetric solutions of supergravity theories. In particular, we explain how spinorial geomet…
Meson decays from string splitting
F. Bigazzi, A. L. Cotrone, L. Martucci +1
We discuss exclusive decays of large spin mesons into mesons in models of large N_c quenched QCD at strong coupling using string theory. The rate of the processes are calculated by…
Twisted Homology
Andres Collinucci, Jarah Evslin
D-branes are classified by twisted K-theory. Yet twisted K-theory is often hard to calculate. We argue that, in the case of a compactification on a simply-connected six manifold, t…
Classification of supersymmetric backgrounds of string theory
U. Gran, J. Gutowski, G. Papadopoulos +1
We review the recent progress made towards the classification of supersymmetric solutions in ten and eleven dimensions with emphasis on those of IIB supergravity. In particular, th…
The energy and stability of D-term strings
Andrés Collinucci, Paul Smyth, Antoine Van Proeyen
Cosmic strings derived from string theory, supergravity or any theory of choice should be stable if we hope to observe them. In this paper we consider D-term strings in D=4, N=1 su…
N=31, D=11
U. Gran, J. Gutowski, G. Papadopoulos +1
We show that eleven-dimensional supergravity backgrounds with thirty one supersymmetries, N=31, admit an additional Killing spinor and so they are locally isometric to maximally su…
Scaling Cosmologies of N=8 Gauged Supergravity
Jan Rosseel, Thomas Van Riet, Dennis B. Westra
We construct exact cosmological scaling solutions in N=8 gauged supergravity. We restrict to solutions for which the scalar fields trace out geodesic curves on the scalar manifold.…
Deformations of calibrated D-branes in flux generalized complex manifolds
Paul Koerber, Luca Martucci
We study massless deformations of generalized calibrated cycles, which describe, in the language of generalized complex geometry, supersymmetric D-branes in N=1 supersymmetric comp…
Effective supergravity descriptions of superstring cosmology
Antoine Van Proeyen
This text is a review of aspects of supergravity theories that are relevant in superstring cosmology. In particular, it considers the possibilities and restrictions for `uplifting…
Gaugino Condensates and D-terms from D7-branes
Michael Haack, Daniel Krefl, Dieter Lust +2
We investigate, at the microscopic level, the compatibility between D-term potentials from world-volume fluxes on D7-branes and non-perturbative superpotentials arising from gaugin…
Nonabelian Global Chiral Symmetry Realisation in the Two-Dimensional N Flavour Massless Schwinger Model
Laure Gouba, Jan Govaerts, M. Norbert Hounkonnou
The nonabelian global chiral symmetries of the two-dimensional N flavour massless Schwinger model are realised through bosonisation and a vertex operator construction.
Bosonization of the Schwinger Model by Noncommutative Chiral Bosons
Joseph Ben Geloun, Jan Govaerts, M. Norbert Hounkonnou
Bosonization of the Schwinger model with noncommutative chiral bosons is considered on a spacetime of cylinder topology. Using point splitting regularization, manifest gauge invari…
Derivative corrections to the Born-Infeld action through beta-function calculations in N=2 boundary superspace
S. Nevens, A. Sevrin, W. Troost +1
We calculate the beta-functions for an open string sigma-model in the presence of a U(1) background. Passing to N=2 boundary superspace, in which the background is fully characteri…
N=31 is not IIB
U. Gran, J. Gutowski, G. Papadopoulos +1
We adapt the spinorial geometry method to investigate supergravity backgrounds with near maximal number of supersymmetries. We then apply the formalism to show that the IIB supergr…
Tits-Satake projections of homogeneous special geometries
Pietro Fre', Floriana Gargiulo, Jan Rosseel +3
We organize the homogeneous special geometries, describing as well the couplings of D=6, 5, 4 and 3 supergravities with 8 supercharges, in a small number of universality classes. T…
Multiple fundamental strings and waves to non-linear order in the background fields
Joke Adam
The Chern-Simons actions of the multiple fundamental string and the multiple gravitational wave are established to full order in the background fields. Gauge invariance is checked.…
Maximally supersymmetric G-backgrounds of IIB supergravity
U. Gran, J. Gutowski, G. Papadopoulos +1
We classify the geometry of all supersymmetric IIB backgrounds which admit the maximal number of -invariant Killing spinors. For compact stability subgroups and S…
Heavy hadron spectra from spin chains and strings
A. L. Cotrone, L. Martucci, J. M. Pons +1
We study the spectrum of hadronic states made up of very massive complex scalar fields in a confining gauge theory admitting a supergravity dual background. We show that for a sub-…
Holographic Wilson Loops
Jaume Gomis, Filippo Passerini
We show that all half-BPS Wilson loop operators in N=4 SYM -- which are labeled by Young tableaus -- have a gravitational dual description in terms of D5-branes or alternatively in…
Geometry of type II common sector N=2 backgrounds
U. Gran, P. Lohrmann, G. Papadopoulos
We describe the geometry of all type II common sector backgrounds with two supersymmetries. In particular, we determine the spacetime geometry of those supersymmetric backgrounds f…
Computational complexity of the landscape I
Frederik Denef, Michael R. Douglas
We study the computational complexity of the physical problem of finding vacua of string theory which agree with data, such as the cosmological constant, and show that such problem…
D-branes on general N=1 backgrounds: superpotentials and D-terms
Luca Martucci
We study the dynamics governing space-time filling D-branes on Type II flux backgrounds preserving four-dimensional N=1 supersymmetry. The four-dimensional superpotentials and D-te…
