摘要

This article proposes a new way of deriving mean-field exponents for sufficiently spread-out Bernoulli percolation in dimensions \(d>6\) d > 6 . We obtain up-to-constant estimates for the full-space and half-space two-point functions in the critical and near-critical regimes. In a companion paper, we apply a similar analysis to the study of the weakly self-avoiding walk model in dimensions \(d>4\) d > 4 [Duminil-Copin and Panis, arXiv:2410.03649, (2024)].
