A Twistor Action for N = 8 Self-dual Supergravity

We give holomorphic Chern-Simons-like action functionals on supertwistor space for self-dual supergravities in four dimensions, with and without gauged R-symmetry or cosmological constant. The gauge group is formally the group of holomorphic contact transformations of supertwistor space. In the case of maximal supersymmetry, we give a formulation in terms of a finite deformation of an integrabl...

Parity Invariance For Strings In Twistor Space

Topological string theory with twistor space as the target makes visible some otherwise difficult to see properties of perturbative Yang-Mills theory. But left-right symmetry, which is obvious in the standard formalism, is highly unclear from this point of view. Here we prove that tree diagrams computed from connected D-instanton configurations are paritysymmetric. The main point in the proof a...

Adding flavour to twistor strings

Twistor string theory is known to describe a wide variety of field theories at tree– level and has proved extremely useful in making substantial progress in perturbative gauge theory. We explore the twistor dual description of a class of N = 2 UV–finite super–Yang– Mills theories with fundamental flavour by adding ‘flavour’ branes to the topological B–model on super-twistor space and comment on...

Twistor theory at fifty: from contour integrals to twistor strings.

We review aspects of twistor theory, its aims and achievements spanning the last five decades. In the twistor approach, space-time is secondary with events being derived objects that correspond to compact holomorphic curves in a complex threefold-the twistor space. After giving an elementary construction of this space, we demonstrate how solutions to linear and nonlinear equations of mathematic...

Self-Dual Supergravity and Twistor Theory

By generalizing and extending some of the earlier results derived by Manin and by Merkulov, a twistor description is given of four-dimensional N -extended (gauged) self-dual supergravity with and without cosmological constant. Starting from the category of (4|4N )-dimensional complex superconformal supermanifolds, the categories of (4|2N )-dimensional complex quaternionic, quaternionic Kähler a...
