On the Factorisation of the Connected Prescription for Yang-Mills Amplitudes
C. Vergu
We examine factorisation in the connected prescription of Yang-Mills amplitudes. The multi-particle pole is interpreted as coming from representing delta functions as meromorphic f…
Moduli Fields as Quintessence and the Chameleon
Philippe Brax, Jerome Martin
We consider models where moduli fields are not stabilized and play the role of quintessence. In order to evade gravitational tests, we investigate the possibility that moduli behav…
Lifetime of a massive particle in a de Sitter universe
Jacques Bros, Henri Epstein, Ugo Moschella
We study particle decay in de Sitter space-time as given by first order perturbation theory in an interacting quantum field theory. We show that for fields with masses above a crit…
On the SU(2|1) WZW model and its statistical mechanics applications
Hubert Saleur, Volker Schomerus
Motivated by a careful analysis of the Laplacian on the supergroup we formulate a proposal for the state space of the WZNW model. We then use properties of $\ha…
Non-renormalisation Conditions in Type II String Theory and Maximal Supergravity
Michael B. Green, Jorge G. Russo, Pierre Vanhove
This paper considers general features of the derivative expansion of Feynman diagram contributions to the four-graviton scattering amplitude in eleven-dimensional supergravity comp…
The Four-Loop Planar Amplitude and Cusp Anomalous Dimension in Maximally Supersymmetric Yang-Mills Theory
Zvi Bern, Michael Czakon, Lance J. Dixon +2
We present an expression for the leading-color (planar) four-loop four-point amplitude of N=4 supersymmetric Yang-Mills theory in 4-2 e dimensions, in terms of eight separate integ…
Moduli Corrections to D-term Inflation
Ph. Brax, C. van de Bruck, A. C. Davis +3
We present a D-term hybrid inflation model, embedded in supergravity with moduli stabilisation. Its novel features allow us to overcome the serious challenges of combining D-term i…
Solution of the H3+ model on a disc
Kazuo Hosomichi, Sylvain Ribault
We determine all the correlators of the H3+ model on a disc with AdS2-brane boundary conditions in terms of correlators of Liouville theory on a disc with FZZT-brane boundary condi…
The WZNW model on PSU(1,1|2)
Gerhard Gotz, Thomas Quella, Volker Schomerus
According to the work of Berkovits, Vafa and Witten (hep-th/9902098), the non-linear sigma model on the supergroup PSU(1,1|2) is the essential building block for string theory on A…
Black String Entropy and Fourier-Mukai Transform
Iosif Bena, Duiliu-Emanuel Diaconescu, Bogdan Florea
We propose a microscopic description of black strings in F-theory based on string duality and Fourier-Mukai transform. These strings admit several different microscopic description…
Mergers and Typical Black Hole Microstates
Iosif Bena, Chih-Wei Wang, Nicholas P. Warner
We use mergers of microstates to obtain the first smooth horizonless microstate solutions corresponding to a BPS three-charge black hole with a classically large horizon area. Thes…
Non-Rational 2D Quantum Gravity II. Target Space CFT
I. K. Kostov, V. B. Petkova
We explore the formulation of non-rational 2D quantum gravity in terms of a chiral CFT on a Riemann surface associated with the target space. The CFT in question is constructed as…
Perturbation theory and stability analysis for string-corrected black holes in arbitrary dimensions
Filipe Moura
We develop the perturbation theory for R^2 string-corrected black hole solutions in d dimensions. After having obtained the master equation and the alpha'-corrected potential under…
Gauge/gravity duality and thermalization of a boost-invariant perfect fluid
Romuald A. Janik, Robi Peschanski
We derive the equation for the quasi-normal modes corresponding to the scalar excitation of a black hole moving away in the fifth dimension. This geometry is the AdS/CFT dual of a…
Coupling Hybrid Inflation to Moduli
Ph. Brax, C. van de Bruck, A. C. Davis +1
Hybrid inflation can be realised in low-energy effective string theory, as described using supergravity. We find that the coupling of moduli to F-term hybrid inflation in supergrav…
Cosmic D-Strings and Vortons in Supergravity
Ph. Brax, C. van de Bruck, A. C. Davis +1
Recent developments in string inspired models of inflation suggest that D-strings are formed at the end of inflation. Within the supergravity model of D-strings there are 2(n-1) ch…
Dark Energy and the MSSM
Philippe Brax, Jerome Martin
We consider the coupling of quintessence to observable matter in supergravity and study the dynamics of both supersymmetry breaking and quintessence in this context. We investigate…
Higher-Derivative Corrected Black Holes: Perturbative Stability and Absorption Cross-Section in Heterotic String Theory
Filipe Moura, Ricardo Schiappa
This work addresses spherically symmetric, static black holes in higher-derivative stringy gravity. We focus on the curvature-squared correction to the Einstein-Hilbert action, pre…
Two-Loop Iteration of Five-Point N=4 Super-Yang-Mills Amplitudes
Z. Bern, M. Czakon, D. A. Kosower +2
We confirm by explicit computation the conjectured all-orders iteration of planar maximally supersymmetric N=4 Yang-Mills theory in the nontrivial case of five-point two-loop ampli…
Fermionic Zero Modes of Supergravity Cosmic Strings
Ph. Brax, C. van de Bruck, A. C. Davis +1
Recent developments in string theory suggest that cosmic strings could be formed at the end of brane inflation. Supergravity provides a realistic model to study the properties of s…
