Vector Supersymmetry: Casimir operators and contraction from OSp(3,2|2)

Roberto Casalbuoni, Federico Elmetti, Joaquim Gomis +3

We study some algebraic properties of the 'vector supersymmetry' (VSUSY) algebra, a graded extension of the four-dimensional Poincare' algebra with two odd generators, a vector and…

The Klebanov-Strassler model with massive dynamical flavors

Francesco Bigazzi, Aldo L. Cotrone, Angel Paredes +1

We present a fully backreacted D3-D7 supergravity solution dual to the Klebanov-Strassler cascading gauge theory coupled to a large number of massive dynamical flavors in the Venez…

Black Holes as Lumps of Fluid

Marco M. Caldarelli, Oscar J. C. Dias, Roberto Emparan +1

The old suggestive observation that black holes often resemble lumps of fluid has recently been taken beyond the level of an analogy to a precise duality. We investigate aspects of…

Non chiral dynamical flavors and screening on the conifold

Francesco Bigazzi, Aldo L. Cotrone, Angel Paredes +1

We present a new class of string theory solutions which are conjectured to be dual to the N=1 conifold theory by Klebanov and Witten coupled to non chiral massive dynamical flavors…

Phase transitions in large N(c) heavy quark potentials

F. Bigazzi, A. L. Cotrone, A. Paredes

We describe phase transitions in the heavy quark potential in planar gauge theories having wrapped D5-brane string duals. A new phase transition, previously unnoticed in these mode…

The elliptic genus from split flows and Donaldson-Thomas invariants

Andres Collinucci, Thomas Wyder

We analyze a mixed ensemble of low charge D4-D2-D0 brane states on the quintic and show that these can be successfully enumerated using attractor flow tree techniques and Donaldson…

First-order flow equations for extremal and non-extremal black holes

Jan Perz, Paul Smyth, Thomas Van Riet +1

We derive a general form of first-order flow equations for extremal and non-extremal, static, spherically symmetric black holes in theories with massless scalars and vectors couple…

Electric/magnetic duality for chiral gauge theories with anomaly cancellation

Jan De Rydt, Torsten T. Schmidt, Mario Trigiante +2

We show that 4D gauge theories with Green-Schwarz anomaly cancellation and possible generalized Chern-Simons terms admit a formulation that is manifestly covariant with respect to…

Quantizing N=2 Multicenter Solutions

Jan de Boer, Sheer El-Showk, Ilies Messamah +1

N=2 supergravity in four dimensions, or equivalently N=1 supergravity in five dimensions, has an interesting set of BPS solutions that each correspond to a number of charged center…

Klebanov-Witten theory with massive dynamical flavors

Francesco Bigazzi, Aldo L. Cotrone, Angel Paredes

We consider the addition of a large number of massive dynamical flavors to the Klebanov-Witten theory, the quiver gauge theory describing the low energy dynamics of Nc D3-branes at…

Generating Geodesic Flows and Supergravity Solutions

E. Bergshoeff, W. Chemissany, A. Ploegh +2

We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacelike reductions of supergravity theories. The geodesics correspond to timelike res…

Heavy quark potential with dynamical flavors: a first order transition

Francesco Bigazzi, Aldo L. Cotrone, Carlos Nunez +1

We study the static potential between external quark-antiquark pairs in a strongly coupled gauge theory with a large number of colors and massive dynamical flavors, using a dual st…

5D fuzzball geometries and 4D polar states

Joris Raeymaekers, Walter Van Herck, Bert Vercnocke +1

We analyze the map between a class of `fuzzball' solutions in five dimensions and four-dimensional multicentered solutions under the 4D-5D connection, and interpret the resulting c…

D-brane Deconstructions in IIB Orientifolds

Andres Collinucci, Frederik Denef, Mboyo Esole

With model building applications in mind, we collect and develop basic techniques to analyze the landscape of D7-branes in type IIB compact Calabi-Yau orientifolds, in three differ…

Les Houches Lectures on Constructing String Vacua

Frederik Denef

These lectures give a detailed introduction to constructing and analyzing string vacua suitable for phenomenological model building, with particular emphasis on F-theory flux vacua…

Real forms of very extended Kac-Moody algebras and theories with eight supersymmetries

Fabio Riccioni, Antoine Van Proeyen, Peter West

We consider all theories with eight supersymmetries whose reduction to three dimensions gives rise to scalars that parametrise symmetric manifolds. We conjecture that these theorie…

Black hole bound states in AdS_3 x S^2

Jan de Boer, Frederik Denef, Sheer El-Showk +2

We systematically construct the geometries dual to the 1+1 dimensional (0,4) conformal field theories that arise in the low-energy description of wrapped M5-branes in S^1 x CY_3 co…

A first-order formalism for timelike and spacelike brane solutions

Bert Janssen, Paul Smyth, Thomas Van Riet +1

We show that the construction of BPS-type equations for non-extremal black holes due to Miller et. al. can be extended to branes of arbitrary dimension and, more importantly, to ti…
