Hadron Production In Pp Collisions Research Articles

Exclusive central hadron production in pp collisions and gluonium contents of resonances

Considering the gluonium contents of resonances, we study the characteristic properties of the π+π-(K+K- mass spectrum for the central reaction pp→pπ+π-(pp→pK+K−p) at very high energies and discuss two-f(1270)-meson production in pomeron-pomeron collisions on the basis of a tensor dominance model.

Diquark fragmentation in p-p interactions and comparison with νp, [formula omitted] interactions

Results on forward hadron production in pp collisions at √ s = 63 GeV with a high p T triggering pion at 30°, are compared with target fragmentation in νp and νp interactions. Pion production is similar in both types of reaction, supporting the concept of universality of diquark fragmentation. Significant differences are observed for proton production.
