A twistor formulation of the heterotic D=10 superstring with manifest (8,0) worldsheet supersymmetry
F. Delduc, A. Galperin, P. Howe +1
We propose a new formulation of the heterotic Green-Schwarz superstring whose worldsheet is a superspace with two even and eight odd coordinates. The action is manifestly in…
Finiteness and anomalies in (4,0) supersymmetric sigma models
P. S. Howe, G. Papadopoulos
Power-counting arguments based on extended superfields have been used to argue that two-dimensional supersymmetric sigma models with (4,0) supersymmetry are finite. This result is…
Holonomy groups and W-symmetries
P. S. Howe, G. Papadopoulos
Irreducible sigma models, i.e. those for which the partition function does not factorise, are defined on Riemannian spaces with irreducible holonomy groups. These special geometrie…
The Superparticle and the Lorentz Group
A. S. Galperin, K. S. Stelle
We present a unified group-theoretical framework for superparticle theories. This explains the origin of the ``twistor-like'' variables that have been used in trading the superpart…
