Abstract
A strong Lorentz-contraction effect of the wave function inside every incoming or outgoing hadron is taken into account in lepton-hadron reactions to understand materialization processes to form jets. A formation of only two jets is derived as a result of coordination of the strongly contracted wave functions. The formalism manifests two distinct models. The one is a strongly ordered cascade model which is in accord with a naive quark-parton cascade model. The other is an uncorrelated jet model which is in accord with an uncorrelated Monte Carlo calculation and it cannot be described as a cascade. Several observable quantities are presented to discriminate between these two models. A space-time evolution in materialization is studied and shown to correspond to an "inside-outside" process.
