Radiative corrections to scalar masses in de Sitter space
T. Brunier, F. Bernardeau, J. -P. Uzan
We compute the radiative corrections to the mass of a test boson field in an inflating space-time. The calculations are carried out in case of a boson part of a supersymmetric chir…
Cosmic Acceleration in Massive Half-Maximal Supergravity
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis
We consider massive half-maximal supergravity in (d+3) dimensions and compactify it on a symmetric three space. We find that the static configurations of Minkowski X S^3, obtained…
Effective actions of a Gauss-Bonnet brane world with brane curvature terms
Ph. Brax, N. Chatillon, D. A. Steer
We consider a warped brane world scenario with two branes, Gauss-Bonnet gravity in the bulk, and brane localised curvature terms. When matter is present on both branes, we investig…
N=4 Super-Yang-Mills Theory, QCD and Collider Physics
Z. Bern, L. J. Dixon, D. A. Kosower
We review how (dimensionally regulated) scattering amplitudes in N=4 super-Yang-Mills theory provide a useful testing ground for perturbative QCD calculations relevant to collider…
All Non-Maximally-Helicity-Violating One-Loop Seven-Gluon Amplitudes in N=4 Super-Yang-Mills Theory
Zvi Bern, Vittorio Del Duca, Lance J. Dixon +1
We compute the non-MHV one-loop seven-gluon amplitudes in N=4 super-Yang-Mills theory, which contain three negative-helicity gluons and four positive-helicity gluons. There are fou…
Loops in Twistor Space
Iosif Bena, Zvi Bern, David A. Kosower +1
We elucidate the one-loop twistor-space structure corresponding to momentum-space MHV diagrams. We also discuss the infrared divergences, and argue that only a limited set of MHV d…
Covariant One-Loop Amplitudes in D=11
L. Anguelova, P. A. Grassi, P. Vanhove
We generalize to the eleven-dimensional superparticle Berkovits' prescription for loop computations in the pure spinor approach to covariant quantization of the superstring. Using…
Localized gravity in non-compact superstring models
Emmanuel Kohlprath, Pierre Vanhove
We discuss a string-theory-derived mechanism for localized gravity, which produces a deviation from Newton's law of gravitation at cosmological distances. This mechanism can be rea…
Boundary Liouville theory at c=1
Stefan Fredenhagen, Volker Schomerus
The c=1 Liouville theory has received some attention recently as the Euclidean version of an exact rolling tachyon background. In an earlier paper it was shown that the bulk theory…
N=2 Liouville Theory with Boundary
Kazuo Hosomichi
We study N=2 Liouville theory with arbitrary central charge in the presence of boundaries. After reviewing the theory on the sphere and deriving some important structure constants,…
All genus correlation functions for the hermitian 1-matrix model
B. Eynard
We rewrite the loop equations of the hermitian matrix model, in a way which allows to compute all the correlation functions, to all orders in the topological expansion, as…
The 4d effective action of 5d gauged supergravity with boundaries
Ph. Brax, N. Chatillon
We consider gauged five dimensional supergravity with boundaries and vector multiplets in the bulk. We analyse the zero modes of the BPS configurations preserving N=1 supergravity…
Next-to-Maximal Helicity Violating Amplitudes in Gauge Theory
David A. Kosower
Using the novel diagrammatic rules recently proposed by Cachazo, Svrcek, and Witten, I give a compact, manifestly Lorentz-invariant form for tree-level gauge-theory amplitudes with…
Soft Supersymmetry Breaking on the Brane
Ph. Brax, N. Chatillon
We consider the low energy description of five dimensional models of supergravity with boundaries comprising a vector multiplet and the universal hypermultiplet in the bulk. We ana…
Ising Field Theory on a Pseudosphere
Benjamin Doyon, Pedro Fonseca
We show how the symmetries of the Ising field theory on a pseudosphere can be exploited to derive the form factors of the spin fields as well as the non-linear differential equatio…
On matrix model partition functions for QCD with chemical potential
G. Akemann, Y. V. Fyodorov, G. Vernizzi
Partition functions of two different matrix models for QCD with chemical potential are computed for an arbitrary number of quark and complex conjugate anti-quark flavors. In the la…
Brane World Cosmology
Philippe Brax, Carsten van de Bruck, Anne--Christine Davis
Recent developments in the physics of extra dimensions have opened up new avenues to test such theories. We review cosmological aspects of brane world scenarios such as the Randall…
Genus one contribution to free energy in hermitian two-matrix model
B. Eynard, A. Kokotov, D. Korotkin
We compute an the genus 1 correction to free energy of Hermitian two-matrix model in terms of theta-functions associated to spectral curve arising in large N limit. We discuss the…
Cross-Order Relations in N=4 Supersymmetric Gauge Theories
C. Anastasiou, Z. Bern, L. J. Dixon +1
The anti-de Sitter/conformal field theory duality conjecture raises the question of how the perturbative expansion in the conformal field theory can resum to a simple function. We…
correction to free energy in hermitian two-matrix model
B. Eynard, A. Kokotov, D. Korotkin
Using the loop equations we find an explicit expression for genus 1 correction in hermitian two-matrix model in terms of holomorphic objects associated to spectral curve arising in…
