Untwisting the twistor superstring
Warren Siegel
The twistor superstring, which describes N=4 super Yang-Mills trees, is taken off-shell (for loops) by generalizing Penrose twistors (which describe on-shell momenta) to Atiyah-Dri…
Stringy gravity at short distances
W. Siegel
Analysis of string interactions indicates a weakening of gravity at the string length scale, thus avoiding black holes and their singularities.
Light-Cone Gauge for N=2 Strings
Olaf Lechtenfeld, Warren Siegel
Covariant quantization of self-dual strings in 2+2 flat dimensions reduces them to their zero modes, a consequence of extended world-sheet supersymmetry. We demonstrate how to arri…
T-Dual Formulation of Yang-Mills Theory
Gordon Chalmers, Warren Siegel
We introduce a self-dual field strength which replaces the gauge field in spontaneously broken Yang-Mills theory, reformulating it as a Lorentz covariant non-linear sigma model. Th…
Manifest Duality in Low-Energy Superstrings
W. Siegel
String theories inspire a new formalism for their low-energy limits. In this approach to these field theories, spacetime duality and stringy left/right handedness are manifest. Enl…
