Parity Invariance For Strings In Twistor Space
نویسنده
چکیده
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 also works for loop diagrams.

The Grassmannian Origin Of Dual Superconformal Invariance
A dual formulation of the S Matrix for N = 4 SYM has recently been presented, where all leading singularities of n-particle Nk−2MHV amplitudes are given as an integral over the Grassmannian G(k, n), with cyclic symmetry, parity and superconformal invariance manifest. In this short note we show that the dual superconformal invariance of this object is also manifest. The geometry naturally sugges...
متن کاملSupertwistors and Cubic String Field Theory for Open N=2 Strings
The known Lorentz invariant string field theory for open N=2 strings is combined with a generalization of the twistor description of anti-self-dual (super) Yang-Mills theories. We introduce a Chern-Simons-type Lagrangian containing twistor variables and derive the Berkovits-Siegel covariant string field equations of motion via the twistor correspondence. Both the purely bosonic and the maximall...
متن کاملSelf - Dual Super - Yang - Mills as a String Theory in ( x , θ ) Space
Different string theories in twistor space have recently been proposed for describing N = 4 super-Yang-Mills. In this paper, my Strings 2003 talk is reviewed in which a string theory in (x, θ) space was constructed for self-dual N = 4 super-Yang-Mills. It is hoped that these results will be useful for understanding the twistor-string proposals and their possible relation with the pure spinor fo...
متن کاملHeterotic Twistor-String Theory
We reformulate twistor-string theory as a heterotic string based on a twisted (0,2) model. The path integral localizes on holomorphic maps, while the (0,2) moduli naturally correspond to the states of N = 4 super Yang-Mills and conformal supergravity under the Penrose transform. We show how the standard twistor-string formulae of scattering amplitudes as integrals over the space of curves in su...
متن کاملAdding 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...
