Fragmentation Spectra in $K^- p$ Interactions at 110-{GeV}/$c$

The Aachen-Berlin-CERN-Cracow-London-Vienna-Warsaw collaboration Gottgens, R. ; Sixel, P. ; Klein, R. ; et al.

The longitudinal momentum spectra of mesons produced in the projectile fragmentation region ofK−p interactions at 110 GeV/c, measured in a bubble chamber experiment, are compared to two fragmentation models related to hadron production by incident leptons. The models give a qualitative description of the data. However, it is found that the mesons having a valence quark in common with the projectile tend to have higher momenta than predicted.

Total and differential cross sections ofK*−(890),K*−(890),\(\bar K^{ * 0} \)(890),K*0(890),\(\bar K^{ * 0} \)(1430) andϱ0(770) produced inK−p interactions at 110 GeV/c are presented. The cross sections of the neutral resonances show a smooth increase with energy from 10 to 110 GeV/c incident momentum. For theK*+(890) and theK*0(890), i.e. the resonances with strangenessS=+1, this rise is quite significant: their cross sections practically double between 32 GeV/c and 110 GeV/c incidentK− momentum. About 50% of the neutral kaons and 30% of charged pions produced inK−p interactions at our energy are found to be decay products of the resonances considered.

Forward and Backward Multiplicities in $K^- p$ Interactions at 110-{GeV}/$c$

The Aachen-Berlin-CERN-Cracow-London-Vienna-Warsaw collaboration Gottgens, R. ; Kohli, J.M. ; Sixel, P. ; et al.

Multiplicity distributions and correlations between charged particles in the forward and back-ward c.m. hemispheres are studied inK−p interactions at 110 GeV/c and compared with other data on mesonnucleon scattering. The interpretation in terms of a simple quark-parton picture assuming that the forward multiplicity is dominated by quark fragmentation and the backward multiplicity by diquark fragmentation is supported by the experimental fact that the forward and the backward mean multiplicities are approximately equal to half of thee+e− andpp multiplicities, respectively. The 110 GeV/cK−p data show significant correlations between the numbers of slow forward and slow backward particles, whereas the multiplicities of fast forward and fast backward particles are independent.
