Summary, in English

In the collinear factorization scheme the minijet cross section diverges for small k [perpendicular]. In the k[perpendicular]-factorization formalism this divergence is avoided, and it is possible to calculate the number of minijets and the E[perpendicular]-flow exclusively from HERA data, without reliance on a phenomenological soft cutoff. The hadron multiplicity is very sensitive to non-perturbative effects. Analyses of minimum bias and underlying events at the Tevatron show that colours appear to combine to give strings, which are as short as possible. This leads to important questions about the properties of the pomeron and the applicability of the AGK cutting rules. ©2006 American Institute of Physics
