Gluon Scattering in Deformed N=4 SYM

Yaron Oz, Stefan Theisen, Shimon Yankielowicz

We consider gluon and gluino scattering amplitudes in large N beta-deformed N=4 SYM with real beta. A direct inspection of the planar diagrams shows that the scattering amplitudes…

Two-Dimensional Quantum Gravity with Boundary

Luzi Bergamin, Rene Meyer

Using the recently found first order formulation of two-dimensional dilaton gravity with boundary, we perform a Hamiltonian analysis and subsequent path integral quantization. The…

Superconformal invariance from N=2 supersymmetry Ward identities

Laurent Baulieu, Guillaume Bossard

We algebraically prove the cancellation of the beta function at all order of perturbation theory of N=2 supersymmetric gauge theories with a vanishing one-loop beta function. The p…

Propagation of light in area metric backgrounds

Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth

The propagation of light in area metric spacetimes, which naturally emerge as refined backgrounds in quantum electrodynamics and quantum gravity, is studied from first principles.…

Is there a tower of charges to be discovered?

T. Mansson

We investigate higher loop integrability for a q-deformation of the su(2)-sector of N=4 SYM theory. First we construct a generalisation of the long range spin chain, which for the…

D-branes on AdS flux compactifications

Paul Koerber, Luca Martucci

We study D-branes in N=1 flux compactifications to AdS_4. We derive their supersymmetry conditions and express them in terms of background generalized calibrations. Basically becau…
