Abstract
High energy particle production data measured with nuclear targets exhibit several outstanding features. These features appear to contradict the naive picture in which the projectile is assumed to propagate “on mass shell” through the nuclear medium by a succession of collisions with single nucleons in the target.
We thank Professors O. Kofoed-Hansen and H. Lipkin for suggesting the use of the word “Collective” rather than “Coherent” in the present context.
This research was performed in collaboration with Prof. A. Dar, Dr. G. Eilam and Mr. Y. Afek.

A more sophisticated approach is possible, whereby a probability is calculated to hit a tube of exactly j nucleons. Physical quantities are then properly weighted with these probabilities and summed over the j’s from 1 to A. See, e.g., reference (2).

Due to the different CM systems of different projectile tube collisions, variables which are not invariant under boosts in the beam direction, such as e.g. the rapidity, must be treated with special care. This treatment is not displayed in eqs. (4) and (5). For details see reference (8).
