Dimensional reduction of higher-point conformal blocks
Sarah Hoback, Sarthak Parikh
Recently, with the help of Parisi-Sourlas supersymmetry an intriguing relation was found expressing the four-point scalar conformal block of a (d-2)-dimensional CFT in terms of a f…

Towards Feynman rules for conformal blocks
Sarah Hoback, Sarthak Parikh
We conjecture a simple set of "Feynman rules" for constructing -point global conformal blocks in any channel in spacetime dimensions, for external and exchanged scalar opera…
