Einteilchenproduktion in K-p-Reaktionen bei 110 GeV/c: eine Analyse im Quarkmodell

One-particle inclusive spectra have been obtained with data of the Big European Bubble Chamber (BEBC) and a multi-wire proportional chamber, namely the External Particle Identifier (EPI). At the beginning of this work the data-summary tapes of the bubble chamber pictures, tapes with the ionization values of the EPI and a program for track extrapolation and pattern recognition were at disposal. In this work the programs are applied on the available data and the acceptance and efficiency of the detector are taken into account with a statistical procedure. New magnetic tapes, which are enriched by the information of the EPI, are produced. With these, one-particle inclusive spectra are obtained, which are compared to various theoretical models for hadronic reactions with small transverse momenta. The models which are taken for the comparison are the dual topological unitarization, the recombination model with structure functions of the Kuti-Weisskopf model, and the spectator quark counting-rules. A statement in the sense that one model is in better agreement with the data than another is possible for the case of outgoing K--mesons. Nevertheless, an independent experiment would be necessary to confirm the statements of this thesis.
