 Random Statistics of OPE Coefficients and Euclidean Wormholes / Belin, Alexandre (CERN) ; de Boer, Jan (Amsterdam U.) We propose an ansatz for OPE coefficients in chaotic conformal field theories which generalizes the Eigenstate Thermalization Hypothesis and describes any OPE coefficient involving heavy operators as a random variable with a Gaussian distribution.
