| Abstract: | Total and differential cross sections for high energy and small momentum transfer elastic hadron-hadron scattering are studied
in QCD using a functional integral approach. The hadronic amplitudes are governed by vacuum expectation values of lightlike
Wegner-Wilson loops, for which a matrix cumulant expansion is derived. The cumulants are evaluated within the framework of
the Minkowskian version of the model of the stochastic vacuum. Using the second cumulant, we calculate elastic differential
cross sections for hadron-hadron scattering. The agreement with experimental data is good.
