TL;DR: In this article, all split helicity gluon tree amplitudes in open twistor string theory were evaluated and it was shown that these amplitudes satisfy the BCFW recurrence relations restricted to the split- helicity case and, hence, the amplitudes agree with those of gauge theory.
Abstract: We evaluate all split helicity gluon tree amplitudes in open twistor string theory. We show that these amplitudes satisfy the BCFW recurrence relations restricted to the split helicity case and, hence, that these amplitudes agree with those of gauge theory. To do this we make a particular choice of the sextic constraints in the link variables that determine the poles contributing to the contour integral expression for the amplitudes. Using the residue theorem to re-express this integral in terms of contributions from poles at rational values of the link variables, which we determine, we evaluate the amplitudes explicitly, regaining the gauge theory results of Britto et al. [25].

TL;DR: In this paper, the authors couple Chern-Simons theory to 3D topological gravity with the aim of investigating its quantum topological invariance, and derive the relevant BRST rules and Batalin-Vilkovisky action.

TL;DR: In this article, it was shown that YM 2 with gauge group SU (N ) is equivalent to a string theory with coupling g s = 1/N, order by order in the 1/ N expansion.

TL;DR: In this article, the authors have explicitly worked out the composite invariants for some framed knots and links carrying composite representations in U (N ) Chern-Simons theory and verified Marino's conjectures on the integrality properties of the topological string amplitudes.
