A Deformation of Twistor Space and a Chiral Mass Term in N = 4 Super Yang-Mills Theory
نویسندگان
چکیده
Super twistor space admits a certain (super) complex structure deformation that preserves the Poincaré subgroup of the symmetry group PSL(4|4) and depends on 10 parameters. In a previous paper [hep-th/0502076], it was proposed that in twistor string theory this deformation corresponds to augmenting N = 4 super Yang-Mills theory by a mass term for the left-chirality spinors. In this paper we analyze this proposal in more detail. We calculate 4-particle scattering amplitudes of fermions, gluons and scalars and show that they are supported on holomorphic curves in the deformed twistor space.

Self - 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 کاملThe Topological B-model on a Mini-Supertwistor Space and Supersymmetric Bogomolny Monopole Equations
In the recent paper hep-th/0502076, it was argued that the open topological Bmodel whose target space is a complex (2|4)-dimensional mini-supertwistor space with D3and D1-branes added corresponds to a super Yang-Mills theory in three dimensions. Without the D1-branes, this topological B-model is equivalent to a dimensionally reduced holomorphic Chern-Simons theory. Identifying the latter with a...
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 کاملScattering Amplitudes and BCFW Recursion in Twistor Space
A number of recent advances in our understanding of scattering amplitudes have been inspired by ideas from twistor theory. While there has been much work studying the twistor space support of scattering amplitudes, this has largely been done by examining the amplitudes in momentum space. In this paper, we construct the actual twistor scattering amplitudes themselves. This gives a formulation of...
متن کاملMassless and Massive Three Dimensional Super Yang-Mills Theory and Mini-Twistor String Theory
We propose various ways of adding mass terms to three-dimensional twistor string theory. We begin with a review of mini-twistor space—the reduction of D = 4 twistor space to D = 3. We adapt the two proposals for twistor string theory, Witten's and Berkovits's, to D = 3 super Yang-Mills theory. In Berkovits's model, we identify the enhanced R-symmetry. We then construct B-model topological strin...
