Modular invariant partition functions for non-compact G/Ad(H) models
Jonas Bjornsson, Jens Fjelstad
We propose a spectrum for a class of gauged non-compact G/Ad(H) WZNW models, including spectrally flowed images of highest, lowest, and mixed extremal weight modules. These are com…
Multi-loop amplitudes in maximally supersymmetric pure spinor field theory
Jonas Bjornsson
This paper provides a more detailed background to the results of arXiv:1004.2692 concerning properties of multi-loop amplitudes in a pure spinor formulation of field theories with…
5 loops in 24/5 dimensions
Jonas Bjornsson, Michael B. Green
A first quantised approach to loop amplitudes based on the pure spinor particle is applied to the systematics of four-particle amplitudes in maximally supersymmetric field theories…
WZNW Strings, Unitarity and Anti de Sitter spaces
Jonas Bjornsson, Stephen Hwang
We investigate the unitarity of strings on non-trivial space-time backgrounds based on gauged WZNW models involving SO(n,2), gauging an SO(n,1) subgroup. As geometric coset spaces,…
Gauged non-compact WZNW models, revisited
Jonas Bjornsson, Stephen Hwang
The purpose of the present paper is to investigate the necessary conditions for unitarity of the spectrum of non-compact gauged WZNW models to some depth. In particular, we would l…
On the unitarity of gauged non-compact world-sheet supersymmetric WZNW models
Jonas Bjornsson, Stephen Hwang
In this paper we generalize our investigation of the unitarity of non-compact WZNW models connected to Hermitian symmetric spaces to the N=1 world-sheet supersymmetric extension of…
