Eur. Phys. J. C44 ()   In high p t quark-quark scattering a simple picture emerges for the colour distribution in the final state: the scattered quark of one of the incident hadrons forms a colour singlet with the spectators of the other hadron, i.e., the four fast coloured objects form two singlets. We assume that the decay of each colour single pair - apart from a trivial boost - is similar to that observed in Cited by: 1. Abstract Measurements of electron, muon, and hadron lateral distributions of extensive air showers as recorded by the KASCADE experiment are by: 10 Parton Shower Evolution!

Mueller, ed., Dimensional analysis of the hadron scattering amplitude in terms of the participating fields yields. We give analytic predictions for angular distributions of hadrons in semi-inclusive and inclusive leptoproduction deduced from first-order calculations in QCD. The predictions allow tests of QCD and give information about gluon fragmentation functions.

  About three decades after the first experiments on deep inelastic lepton hadron scattering began to investigate the structure of hadrons, the history of this fruitful field of particle physics continues in the broad spectrum of research performed at the electron and positron proton collider HERA at DESY, where the multipurpose detectors ZEUS and H1 access ep scattering at a center of mass. ANALYTICAL DESCRIPTION OF HADRON-HADRON SCATTERING VIA PRINCIPLE OF MINIMUM DISTANCE IN SPACE OF STATES D. B. ION1,2, M. L. D. ION3 1 IFIN-HH, Bucharest, P.O. Box MG-6, Mãgurele, Romania 2 TH-Division, CERN, CH Gen Switzerland 3 Faculty of Physics, Bucharest University, Bucharest, Romania Received J In this paper an analytical description of the hadron-hadron scattering is. 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.
