[en] Long-range correlations, as observed at the ISR, can easily be described by a picture of overlapping independent emission (OIE). In this picture, hadronic production is viewed as an incoherent superposition of elementary bremsstrahlung components. By selecting events with fixed values of the multiplicity in one hemisphere, one arrives at samples with strongly reduced long range correlations. At very high energies, these samples represent elementary bremsstrahlung components whose factual existence corroborates the OIE model. (Auth.)
