Hadron production inπ+,K+p andpp collisions at 147 GeV/c and properties of jet-like multiparticle systems

The gross features of the data are reviewed and the momentum tensor components, 〈S〉, and 〈T〉 are studied. Evidence for coplanarity effects is observed. A probabilistic method to search for jets is proposed. The jets found by this method are seen to be similar to highp T jets frompp interactionse+e− annihilations andvp interactions. The effect of subtracting the leading particles and the effect of lowp T diffractive and non diffractive components are investigated.
