Selberg’s central limit theorem states that the values of, whereτis a uniform random variable on, are asymptotically distributed like a Gaussian random variable of mean 0 and standard deviation. It was conjectured by Radziwiłł that this distribution breaks down for values of order, where a multiplicative correctionCkwould be present at level,k> 0. This constant should be the same as the one conjectured by Keating and Snaith for the leading asymptotic of themoment ofζ. In this paper, we provide numerical and theoretical evidence for this conjecture. We propose that this correction has a significant effect on the distribution of the maximum ofin intervals of size. The precision of the prediction enables the numerical detection ofCkeven for lowT’s of order. A similar correction appears in the large deviations of the Keating–Snaith central limit theorem for the logarithm of the characteristic polynomial of a random unitary matrix, as first proved by Féray, Méliot and Nikeghbali.
