Using the explicit computation of the scalar products of bethe states and a revisited version of the bulk quantum inverse problem, we calculate the elementary building blocks for the correlation functions. Even for this model only the nearest neighbor and the second neighbor correlations were known.

After providing the necessary foundations for treating correlation functions at finite temperatures in section 2 we derive our main result in section 3, which is the integral formula in theorem 1. Correlation functions of the xxz model in the massive and massless regimes are known to satisfy a system of linear equations.
