Résumé

We discuss the 4pt function of the critical 3d Ising model, extracted from recent conformal bootstrap results.We focus on the non-gaussianity Q -the ratio of the 4pt function to its gaussian part given by three Wick contractions.This ratio reveals significant non-gaussianity of the critical fluctuations.The bootstrap results are consistent with a rigorous inequality due to Lebowitz and Aizenman, which limits Q to lie between 1/3 and 1.
