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.
