## Abstract

Assuming the Riemann Hypothesis (RH), Montgomery proved a theorem in 1973 concerning the pair correlation of zeros of the Riemann zeta-function and applied this to prove that at least $2/3$ of the zeros are simple. In this paper, we investigate the versatility of the pair correlation method and show, for the first time, that it can be used to prove results on the \\emph{horizontal distribution} of zeros of the Riemann zeta-function.   In earlier work we showed how to remove RH from Montgomery's theorem and, in turn, obtain results on simple zeros assuming conditions on the zeros that are weaker than RH. Here we assume a more general condition, namely that all the zeros $\\rho = \\beta +i\\gamma$ with $T\<\\gamma\\le 2T$ are in a narrow vertical box centered on the critical line with width $b/\\log T$, where $b\\to 0$ as $T\\to \\infty$. We first prove the generalization of Montgomery's result that at least $2/3$ of zeros are simple, and we then prove the new result that the pair correlation method yields at least $2/3$ of the zeros on the critical line. We also use the pair correlation method to prove that at least $1/3$ of the zeros are both simple and on the critical line, a result already known unconditionally using different methods.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
