INTERMITTENCY (A Review of Experimental Results) W. KITTEL

Apart from some misunderstandings of this summer, recent developments have led to considerable progress in this controversial but challenging eld. Intermittency is now established as an eeect in at least two dimensions, where it has turned out to be stronger and cleaner than in one. The eeect is strongest in e + e ? collisions at LEP energies. At these energies parton showering has become a good candidate to explain intermittency and it could be tried as a model for other types of collision. Before that, however, the exact origin of intermittency in the shower Monte Carlo should become clear and the model should be checked on the more sensitive transverse momentum and multiplicity dependence of the eeect. Next to parton showering, intermittency is very sensitive to the soft phase, which will have to be studied in more detail at lower energies. Further insight is expected from factorial correlators, from the use of other types of moments and from the study of individual \spiky" events.
