Abstract

We prove that the correction to exponential decay of the truncated two points function in the homogeneous positive field Ising model is cx(d1)/2c\|x\|^{-(d-1)/2}. The proof is based on the development in the random current representation of a "modern" Ornstein-Zernike theory, as developed by Campanino, Ioffe and Velenik.
