  By using predictions from the Pythia 8 Monte Carlo event generator, we
determine the energy-dependent turn-over values (pT0) of the partonic cross
section for the simulation of multiparton interactions. Since the observed
energy dependence of the pT0 values is not well described by a power-law
function, we introduce an additional energy-dependent term, to better describe
the experimental observations in the energy range sqrt(s) = 0.3-13 TeV. We
obtain a similar level of agreement for predictions using various parton
densities.
