A structural test for the conformal invariance of the critical 3d Ising model
Simao Meneses, Joao Penedones, Slava Rychkov +2
How can a renormalization group fixed point be scale invariant without being conformal? Polchinski (1988) showed that this may happen if the theory contains a virial current -- a n…

Remarks on the Convergence Properties of the Conformal Block Expansion
Slava Rychkov, Pierre Yvernay
We show how to refine conformal block expansion convergence estimates from hep-th/1208.6449. In doing so we find a novel explicit formula for the 3d conformal blocks on the real ax…
