Towards an exact frame formulation of conformal higher spins in three dimensions
Bengt E. W. Nilsson
In this note we discuss some aspects of the frame formulation of conformal higher spins in three dimensions. We give some exact formulae for the coupled spin two - spin three part…
Fourier expansions of Kac-Moody Eisenstein series and degenerate Whittaker vectors
Philipp Fleig, Axel Kleinschmidt, Daniel Persson
Motivated by string theory scattering amplitudes that are invariant under a discrete U-duality, we study Fourier coefficients of Eisenstein series on Kac-Moody groups. In particula…
Second Quantized Mathieu Moonshine
Daniel Persson, Roberto Volpato
We study the second quantized version of the twisted twining genera of generalized Mathieu moonshine, and prove that they give rise to Siegel modular forms with infinite product re…
Non-Lagrangian Theories from Brane Junctions
Ling Bao, Vladimir Mitev, Elli Pomoni +2
In this article we use 5-brane junctions to study the 5D T_N SCFTs corresponding to the 5D N=1 uplift of the 4D N=2 strongly coupled gauge theories, which are obtained by compactif…
The trouble with twisting (2,0) theory
Louise Anderson, Hampus Linander
We consider a twisted version of the abelian theory placed upon a Lorenzian six-manifold with a product structure, . This is done by an investigation of…
A new pentagon identity for the tetrahedron index
Ilmar Gahramanov, Hjalmar Rosengren
Recently Kashaev, Luo and Vartanov, using the reduction from a four-dimensional superconformal index to a three-dimensional partition function, found a pentagon identity for a spec…
Pure spinor superfields -- an overview
Martin Cederwall
Maximally supersymmetric theories do not allow off-shell superspace formulations with traditional superfields containing a finite set of auxiliary fields. It has become clear that…
Index theory and dynamical symmetry enhancement near IIB horizons
U. Gran, J. Gutowski, G. Papadopoulos
We show that the number of supersymmetries of IIB black hole horizons is N=2 N_- + 2 index(D_λ), where index(D_λ) is the index of the Dirac operator twisted with the line bundle λ^…
IIB horizons
U. Gran, J. Gutowski, G. Papadopoulos
We solve the Killing spinor equations for all near-horizon IIB geometries which preserve at least one supersymmetry. We show that generic horizon sections are 8-dimensional almost…
Radiation reaction from QED: lightfront perturbation theory in a plane wave background
Anton Ilderton, Greger Torgrimsson
We derive dynamical, real time radiation reaction effects from lightfront QED. Combining the Hamiltonian formalism with a plane wave background field, the calculation is performed…
Critical solutions in topologically gauged N=8 CFTs in three dimensions
Bengt E. W. Nilsson
In this paper we discuss some special (critical) background solutions that arise in topological gauged three-dimensional CFTs with SO(N) gauge group. These solutio…
Exceptional geometry and tensor fields
Martin Cederwall, Joakim Edlund, Anna Karlsson
We present a tensor calculus for exceptional generalised geometry. Expressions for connections, torsion and curvature are given a unified formulation for different exceptional grou…
Non-gravitational exceptional supermultiplets
Martin Cederwall
We examine non-gravitational minimal supermultiplets which are based on the tensor gauge fields appearing as matter fields in exceptional generalised geometry. When possible, off-s…
Five-dimensional topologically twisted maximally supersymmetric Yang-Mills theory
Louise Anderson
Herein, we consider a topologically twisted version of maximally supersymmetric Yang-Mills theory in five dimensions which was introduced by Witten in 2011. We consider this theory…
Loop amplitudes in maximal supergravity with manifest supersymmetry
Martin Cederwall, Anna Karlsson
We present a description for amplitude diagrams in maximal supergravities obtained by dimensional reduction from D=11, derived from a field theory point of view using the pure spin…
Radiation reaction in strong field QED
Anton Ilderton, Greger Torgrimsson
We derive radiation reaction from QED in a strong background field. We identify, in general, the diagrams and processes contributing to recoil effects in the average momentum of a…
