Diagonal Limit for Conformal Blocks in d Dimensions
Matthijs Hogervorst, Hugh Osborn, Slava Rychkov
Conformal blocks in any number of dimensions depend on two variables z, zbar. Here we study their restrictions to the special "diagonal" kinematics z = zbar, previously found usefu…

Radial Coordinates for Conformal Blocks
Matthijs Hogervorst, Slava Rychkov
We develop the theory of conformal blocks in CFT_d expressing them as power series with Gegenbauer polynomial coefficients. Such series have a clear physical meaning when the confo…
