TL;DR: In this paper, a study of centrally produced mesons in 3 × 106 events with two small-angle protons at the CERN Intersecting Storage Rings is presented, where the reaction mechanism is dominated by double pomeron exchange.

TL;DR: In this article, all charged particles of transverse momentum p T between 1.5 and 4.4 GeV/c at center of mass angles 90° and 59.4° from p-p-collisions with √ s = 44 and 53 GeV has been measured.

TL;DR: In this article, the authors extracted the cross section for two-constituent hard scattering for pT between 6 and 14 GeV at y = 0 and showed that the decrease of this jet cross section over this pT range is consistent with exp (−bpT), with b = (1.02 ± 0.09) GeV−1.

TL;DR: In this article, Bose-Einstein correlations between pions produced in the central region of rapidity in α, pp and p p interactions have been studied at the ISR, and the parameters r and τ c -often interpreted as the radius and depth of the π-emitting region - are found to be independent of incident particle type but to depend on the mean charged multiplicity.
