New Formulae for Gravity Amplitudes: Parity Invariance and Soft Limits
Mathew Bullimore
Cachazo and Skinner have recently conjectured a new formula for the complete tree-level S-matrix of N = 8 supergravity. The formula is an integral over the moduli space of rational…

Holomorphic Linking, Loop Equations and Scattering Amplitudes in Twistor Space
Mathew Bullimore, David Skinner
We study a complex analogue of a Wilson Loop, defined over a complex curve, in non-Abelian holomorphic Chern-Simons theory. We obtain a version of the Makeenko-Migdal loop equation…

Kinetic mixing of U(1)s for local string models
Mathew Bullimore, Joseph P. Conlon, Lukas T. Witkowski
We study kinetic mixing between massless U(1)s in toroidal orbifolds with D3-branes at orbifold singularities. We focus in particular on C^3/Z_4 singularities but also study C^3/Z_…
