Two - Component Model for the Associated Multiplicity in Inclusive Reactions
نویسندگان
چکیده
We present a simple, two-component model for the charged mu'ltiplicity associated with the observed particle in an inclusive reaction. At small p T' the scattering is ascribed to a coherent or I* soft " component, whereas at large pT the production mechanism is assumed to be incoherent or " hard. l1 At fixed incident energy and missing mass, the pT-dependence of Kc is given by the relative weights of hard and soft scattering, so that the multiplicity is a sensitive probe of the transition region between the two components. The model is applied to recent multiplicity data for pp-pX and pp-?r+X at 28.5 GeV/c, as well as data at Fermilab and ISR energies.

متن کاملMultiple-Scattering Model for Inclusive Proton Production in Heavy Ion Collisions
A formalism is developed for evaluating the momentum distribution for proton production in nuclear abrasion during heavy ion collisions using the Glauber multiple-scattering series. Several models for the onebody density matrix of nuclei are considered for performing numerical calculations. Calculations for the momentum distribution of protons in abrasion are compared with experimental data for...
