“…-0 0 In ref. [20] we find that if in the reaction n p -» p A , we increase the mass of the n-ir system till we reach the reaction n~p -if A, the density matrix elements in the very small t' region remain the same. One finds, for example that p Q0 = 0.91 ± 0.07 for 0 < t* -t'.…”

“…While the range of validity of the PPD hypothesis may be controversial, it seems very clear from a study of quasi-twobody reactions that there definitely exists a range of small t* over which the amplitude factorizes to a very good approximation and is dominated by the pion pole. For example, at very small t', all density matrix elements approach + he PPD values [19][20][21]. To extend this result from the quasi-two-body reactions to the double-pomeron process, one simply needs to increase the masses of the end blobs from the re-onance region to the pomeron region.…”

The clustering of events in 7-dimensional phase space is studied in the reactions z f p + pnf n* n-at 16 GeV/c. The Yang variables are used for locating eventa in the phase space. Clusters are defined and events are allocated by a novel iterative technique. This is baaed on a measure of the distance of each event from the cluster centre, weighted by the covariance matrix of the event density. The clusters found are then related to reaction mechanisms such as diffraotion dissociation of pion and proton, resonance production, etc. High mass enhancements in the (3z) system and in the ( p n f n -) system are identified and separated from other mechanisms. Cross sections are given for individual sub-channels and compared to results obtained by other techniques.
