Query: Double parton scattering: Impact of nonperturbative parton correlations   We apply the phenomenological Reggeon Field Theory framework to investigate
the relative importance of perturbative and nonperturbative multiparton
correlations for the treatment of double parton scattering (DPS) in
proton-proton collisions. We obtain a significant correction to the so-called
effective cross section for DPS due to nonperturbative parton splitting. When
combined with the corresponding perturbative contribution, this results in a
rather weak energy and transverse momentum dependence of the effective cross
section, in agreement with experimental observations at the Tevatron and the
Large Hadron Collider. In addition, we observed that color fluctuations have a
sizable impact on the calculated rate of double parton scattering and on the
relative importance of the perturbative parton splitting mechanism.
