Horizons cannot save the Landscape
Iosif Bena, Alex Buchel, Oscar J. C. Dias
Solutions with anti-D3 branes in a Klebanov-Strassler geometry with positive charge dissolved in fluxes have a certain singularity corresponding to a diverging energy density of th…
SUPER-Screening
Philippe Brax, Anne-Christine Davis, Jeremy Sakstein
We present a framework for embedding scalar-tensor models of screened modifed gravity such as chameleons, symmetrons and environmental dilatons into global supersymmetry. This achi…
Polchinski-Strassler does not uplift Klebanov-Strassler
Iosif Bena, Mariana Grana, Stanislav Kuperstein +1
Anti-D3-branes at the tip of the Klebanov-Strassler solution with D3-charge dissolved in fluxes give rise, in the probe approximation, to a metastable state. The fully back-reacted…
Lattice W-algebras and logarithmic CFTs
A. M. Gainutdinov, H. Saleur, I. Yu. Tipunin
This paper is part of an effort to gain further understanding of 2D Logarithmic Conformal Field Theories (LCFTs) by exploring their lattice regularizations. While all work so far h…
A physical approach to the classification of indecomposable Virasoro representations from the blob algebra
Azat M. Gainutdinov, Jesper Lykke Jacobsen, Hubert Saleur +1
In the context of Conformal Field Theory (CFT), many results can be obtained from the representation theory of the Virasoro algebra. While the interest in Logarithmic CFTs has been…
Generalized N=1 and N=2 structures in M-theory and type II orientifolds
Mariana Graña, Hagen Triendl
We consider M-theory and type IIA reductions to four dimensions with N=2 and N=1 supersymmetry and discuss their interconnection. Our work is based on the framework of Exceptional…
Bootstrapping Conformal Field Theories with the Extremal Functional Method
Sheer El-Showk, Miguel F. Paulos
The existence of a positive linear functional acting on the space of (differences between) conformal blocks has been shown to rule out regions in the parameter space of conformal f…
D = 5 maximally supersymmetric Yang-Mills theory diverges at six loops
Zvi Bern, John Joseph Carrasco, Lance J. Dixon +3
The connection of maximally supersymmetric Yang-Mills theory to the (2,0) theory in six dimensions has raised the possibility that it might be perturbatively ultraviolet finite in…
Jet evolution from weak to strong coupling
Y. Hatta, E. Iancu, A. H. Mueller +1
Recent studies, using the AdS/CFT correspondence, of the radiation produced by a decaying system or by an accelerated charge in the N=4 supersymmetric Yang-Mills theory, led to a s…
Unitarity and fuzzball complementarity: "Alice fuzzes but may not even know it!"
Steven G. Avery, Borun D. Chowdhury, Andrea Puhm
We investigate the recent black hole firewall argument. For a black hole in a typical state we argue that unitarity requires every quantum of radiation leaving the black hole to ca…
Equivalent D=3 Supergravity Amplitudes from Double Copies of Three-Algebra and Two-Algebra Gauge Theories
Yu-tin Huang, Henrik Johansson
We show that three-dimensional supergravity amplitudes can be obtained as double copies of either three-algebra super-Chern-Simons matter theory or that of two-algebra super-Yang-M…
On-shell recursion for massive fermion currents
Ruth Britto, Alexander Ochirov
We analyze the validity of BCFW recursion relations for currents of n - 2 gluons and two massive quarks, where one of the quarks is off shell and the remaining particles are on she…
The Effective Field Theory of Dark Energy
Giulia Gubitosi, Federico Piazza, Filippo Vernizzi
We propose a universal description of dark energy and modified gravity that includes all single-field models. By extending a formalism previously applied to inflation, we consider…
Screening fifth forces in k-essence and DBI models
Philippe Brax, Clare Burrage, Anne-Christine Davis
New fifth forces have not yet been detected in the laboratory or in the solar system, hence it is typically difficult to introduce new light scalar fields that would mediate such f…
Seiberg-Witten equations and non-commutative spectral curves in Liouville theory
Leonid Chekhov, Bertrand Eynard, Sylvain Ribault
We propose that there exist generalized Seiberg-Witten equations in the Liouville conformal field theory, which allow the computation of correlation functions from the resolution o…
Six-loop Konishi anomalous dimension from the Y-system
Sebastien Leurent, Didina Serban, Dmytro Volin
We compute the Konishi anomalous dimension perturbatively up to six loop using the finite set of functional equations derived recently by Gromov, Kazakov, Leurent and Volin. The re…
Non-extremal Black Hole Microstates: Fuzzballs of Fire or Fuzzballs of Fuzz ?
Iosif Bena, Andrea Puhm, Bert Vercnocke
We construct the first family of microstate geometries of near-extremal black holes, by placing metastable supertubes inside certain scaling supersymmetric smooth microstate geomet…
Kerr-AdS and its Near-horizon Geometry: Perturbations and the Kerr/CFT Correspondence
Oscar J. C. Dias, Jorge E. Santos, Maren Stein
We investigate linear perturbations of spin-s fields in the Kerr-AdS black hole and in its near-horizon geometry (NHEK-AdS), using the Teukolsky master equation and the Hertz poten…
Is Alice burning or fuzzing?
Borun D. Chowdhury, Andrea Puhm
Recently, Almheiri, Marolf, Polchinski and Sully (AMPS) have suggested a Gedankenexperiment to test black hole complementarity. They claim that the postulates of black hole complem…
Two-Loop Maximal Unitarity with External Masses
Henrik Johansson, David A. Kosower, Kasper J. Larsen
We extend the maximal unitarity method at two loops to double-box basis integrals with up to three external massive legs. We use consistency equations based on the requirement that…
One-loop four-graviton amplitudes in N=4 supergravity models
Piotr Tourkine, Pierre Vanhove
We evaluate in great detail one-loop four-graviton field theory amplitudes in pure N=4 D=4 supergravity. The expressions are obtained by taking the field theory limits of (4,0) and…
N=2 supersymmetric AdS_4 solutions of M-theory
Maxime Gabella, Dario Martelli, Achilleas Passias +1
We analyse the most general N=2 supersymmetric solutions of D=11 supergravity consisting of a warped product of four-dimensional anti-de-Sitter space with a seven-dimensional Riema…
N=2 vacua in Generalized Geometry
Mariana Graña, Francesco Orsi
We find the conditions on compactifications of type IIA to four-dimensional Minkowski space to preserve N=2 supersymmetry in the language of Exceptional Generalized Geometry (EGG)…
The Five-Loop Four-Point Amplitude of N=4 super-Yang-Mills Theory
Z. Bern, J. J. M. Carrasco, H. Johansson +1
Using the method of maximal cuts, we construct the complete D-dimensional integrand of the five-loop four-point amplitude of N = 4 super-Yang-Mills theory, including nonplanar cont…
