The One-Loop QCD -Function as an Index
Roland Bittleston, Kevin Costello
In this letter we show that the one-loop QCD -function can be obtained from an index theorem on twistor space. This is achieved by recalling that the -angle of self-dual ga…
Non-Commutative Gauge Theory at the Beach
Roland Bittleston, Simon Heuveline, Surya Raghavendran +1
The KP equation is perhaps the most famous example of a three-dimensional integrable system. Here we show that a non-commutative five-dimensional Chern-Simons theory living on the…
Self-Dual Gauge Theory from the Top Down
Roland Bittleston, Kevin Costello, Keyou Zeng
We introduce a family of dualities between certain non-supersymmetric self-dual gauge theories on a large class of self-dual asymptotically flat backgrounds, and the large …
The Self-Duality Equations on a Riemann Surface and Four-Dimensional Chern-Simons Theory
Roland Bittleston, Lionel Mason, Seyed Faroogh Moosavian
We construct a Lagrangian formulation of Hitchin's self-duality equations on a Riemann surface using potentials for the connection and Higgs field. This two-dimensional action…
Scattering in Instanton Backgrounds
Roland Bittleston, Kevin Costello
In this letter we evaluate one-loop all-plus gluon amplitudes of gauge theory with fundamental fermions in the presence of a flavour instanton background.…
