Abstract:
Motivated by the correlation functions-Wilson loop correspondence in
maximally supersymmetric Yang-Mills theory, we will investigate a
conjecture of Alday, Buchbinder, and Tseytlin regarding correlators of
null polygonal Wilson loops with local operators in general position.
By translating the problem to twistor space, we can show that such
correlators arise by taking null limits of correlation functions in the
gauge theory, thereby providing a proof for the conjecture.
Additionally, twistor methods allow us to derive a recursive formula for
computing these correlators, akin to the BCFW recursion for scattering
amplitudes. |
