Hadron final states in deep inelastic processes

Abstract

In summary, we have found that the picture of space-time evolution of hadron final states in deep inelastic processes isn't totally trivial, and also have found that it can be made consistent with the hypotheses of the parton model (and therefore also with the trends of the data at present). This is only the case provided that there exist long-range rapidity correlations in the deep inelastic dynamics. This is in fact what is indicated in two dimensional quantum electrodynamics, as discovered by Casher, Kogut and Susskind. It strongly suggests the relevance of some kind of gauge theory as a necessary element in the interpretation of the confinement problem. Finally it is clear that the discussion above is so qualitative that while hopefully providing some insight into the space-time geography of what is going on, it is a far cry from what we should like to have in order to make quantitative comparisons with experiment. In fact, I see the above description as a solution to a problem which hasn't been well defined. The problem remaining is to try to sharpen the above considerations by specifying precisely what the problem is that is to be solved. Perhaps it is a variant of the Landau hydrodynamic model, but one which incorporates the concepts of short range correlation in rapidity instead of Landau's concept of total arrest of hadronic matter in hadron-hadron collisions. If such a hydrodynamic picture could be worked out it might lead to some further insights into the dynamics of confinement and of deep inelastic processes.
