In standard potential-model descriptions of the Be7(p,gamma)B8 reaction the Be7+p spectroscopic factors S appear in the cross section. We argue that the microscopic substructure effects which are represented by S are short-ranged and cannot…
QCD predictions for moments of multiplicity distributions are compared with experimental data on e+e- collisions and their two-NBD fits. Moments of the multiplicity distribution in a two-NBD model for 1.8 TeV pp collisions are considered.…
