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…

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 …

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.…
