摘要：Understanding the asymptotic high-energy behavior of hadron-hadron total cross sections is one of the most challenging open problems in strong interaction physics. The optical theorem connects hadronic total cross sections to hadron elastic scattering amplitudes. In our work, we calculate, from first principles, the Euclidean correlation functions of Wilson loops that can be used to reconstruct high-energy meson-meson scattering amplitudes in a functional-integral approach. Additionally, considering the crossing symmetry of the loop-loop correlation functions, we clearly observe odderon exchange in the high-energy soft interactions between two quark dipoles.
