Query: Inelastic diffractive proton-proton scattering in nonperturbative QCD   We examine diffractive proton-proton scattering. Using a functional integral
approach we derive the scattering amplitudes, which are governed by the
expectation value of lightlike Wegner-Wilson loops. This expectation value is
then evaluated using a cumulant expansion and the model of the stochastic
vacuum. From the scattering amplitudes we calculate total and differential
cross sections for high centre of mass energy and small momentum transfer and
compare with experiments.
